The Knife Is Cast into the Sea

by Horace R. Coke, Simulacrum · Universitas Scholarium

There is a radiator under the witness box at the Coroner's Court in Tennis Street, Southwark, and it ticks. It ticked all through the three days of the inquest into the death of Stanley Peploe, a retired lighterman of eighty-four who was found in his flat in Rotherhithe on the fifteenth of January with the temperature in his sitting room at nine degrees. Every witness gave evidence about the cold with warm ankles. I noticed it on the first morning and could not stop noticing it, as you cannot stop hearing a clock once someone has mentioned it.

My client sat beside Delia Ormerod in the second row, in a suit bought for the occasion, with the price ticket still on the cuff of the left sleeve. I took it off for him with my penknife before the coroner came in. His name was Gary Tullett, he was twenty-seven, and until February he had been a Night Resolution Supervisor at the Croydon contact centre of Riverlink Homes, which owns some eleven thousand flats south of the river, Mr Peploe's among them. Since February he had been suspended on full pay, which is what an employer does when it has decided you are guilty but has not yet found the paperwork.

Nobody had accused him of anything. An inquest accuses nobody. Section 10 of the Coroners and Justice Act forbids a coroner to frame her conclusion so as to appear to decide the criminal liability of a named person, or any civil liability at all. It is a court that asks how a man died and is forbidden to ask whose fault it was. But Riverlink's solicitors had written to the coroner in the summer, in a letter Delia had obtained, and the letter said that the failure had occurred "at the human review stage". There was only one human at the human review stage on the night in question. His price ticket was in my waistcoat pocket.

"They're going to say it was me," he said, when I sat down.

"They are going to try very hard not to say it," I told him. "That is how you'll know they mean it."

The facts took a morning, and I will give them to you quicker than that.

On the sixth of January, during the cold snap, Mr Peploe's daughter, Mrs Maureen Sallis, sent a message through the Riverlink app from her kitchen in Gravesend. The coroner had it read out, and I set it down as it was written, because the punctuation turned out to matter.

Dads boiler gone again no heating no hot water. hes 84. hes got the little fan heater but he wont put it on because of the meter. please can someone come

The message was received by an automated agent which Riverlink calls Hestia. I gather the name was chosen by a marketing consultancy, after the Greek goddess of the hearth, and that the consultancy was paid more for the name than Mr Peploe had been paid for his last year on the river. Hestia read the message in rather less than a second. It sorted it under Heating — Full Loss, noted Temporary heating available, and gave it Priority 3, which at Riverlink means an engineer within twenty-eight days. It then put it in a batch with forty-nine other requests and sent the batch for human review.

At twelve minutes past three in the morning of the seventh, Gary Tullett approved the batch.

An engineer was booked for the twenty-ninth. Mrs Sallis rang twice and was told that the job was "in the system". On the fifteenth she drove up from Gravesend with a casserole and found her father in his armchair by the fan heater, which was unplugged, with his coat on. The pathologist said hypothermia, and said it in a quiet voice.

Riverlink's witness was a Mrs Carol Denholm, Head of Customer Operations, a pleasant woman in a navy suit who called the requests "contacts" and the tenants "customers" and Mr Peploe, once, by mistake, "the customer", and then corrected herself, and coloured. Her counsel, Miss Antonia Brewster, took her through the system. It had, she said, a human in the loop. Hestia proposed; a trained supervisor disposed. That safeguard had been built in from the start, at the board's insistence, and a trained supervisor could read and consider a message, where he needed to, in about twenty seconds.

When it was my turn I stood up and asked about the loop.

"Mrs Denholm, how many contacts did Mr Tullett review on the night of the sixth?"

She had the figure. People always have the figure they are proud of. "Three thousand one hundred and forty."

"In a shift of?"

"Ten hours. With a forty-minute break."

"So nine hours and twenty minutes. Five hundred and sixty minutes. Thirty-three thousand six hundred seconds." I had worked it out on the back of the coroner's list the night before, with a pencil and a glass of Château Thames Embankment, and I read it out slowly, as if I were doing it now. "Divided by three thousand one hundred and forty. Madam, my arithmetic is that of a man who was taught it with chalk. Would you agree that it comes to a little under eleven seconds for each contact?"

"The system is designed to be efficient."

"I'm sure it is. Now. When Mr Tullett looked at a batch on his screen, what did he see?"

She described it. A grid, fifty rows, one for each contact. On each row a reference number, a category, a priority and a little green tick, which was Hestia's way of saying it was confident.

"And the customer's message itself? Mrs Sallis's words?"

"Those are available."

"Available where?"

"If the supervisor clicks on the row, the message opens in a side panel."

"If he clicks. And if he clicks on all fifty rows, and reads all fifty messages, how long does a batch take him?"

"I couldn't say."

"Let me help you. You told Miss Brewster that a message takes an average of twenty seconds to read and consider. Fifty times twenty is a thousand seconds; a little under seventeen minutes a batch. Sixty-three batches, near enough, in the night. That is about seventeen and a half hours of reading in a shift of nine hours and twenty minutes. Who decided that the words should be behind a click?"

"It was a design decision. To reduce cognitive load."

"Whose cognitive load, Mrs Denholm? Mr Tullett's, or the board's?"

Miss Brewster rose to object, and the coroner, a Mrs Arkwright, a lean grey woman with reading glasses on a cord, looked at me over them and said that she thought the question had answered itself, and that I might move on. I moved on. It is the most a coroner can give you, and more than most judges do.

"One more, Mrs Denholm. If Mr Tullett had opened every message and read it, and approved, let us say, a thousand contacts in the night instead of three thousand, what would have happened to him?"

There was a pause, and in the pause the radiator ticked.

"He would have been spoken to about his productivity."

"Spoken to. And if it happened again?"

"There's a process."

"Thank you. I've no doubt there is."

The second day belonged to Mr Julian Hapgood, King's Counsel, who appeared for Calloway Systems Limited, which had made Hestia and leased it to Riverlink at six pence a contact. Hapgood is a tall, beautifully barbered man who practises in the Chancery Division and has never, I think, smelt a cell. He was courteous to everyone. That is the kind of opponent to be afraid of.

His case was extremely candid, and extremely clever, and the candour was the clever part. Calloway's head of engineering, a soft-spoken young woman named Dr Priya Halloran, told the coroner without being asked that version 1.9 of Hestia had possessed what she called "a known weakness with negated availability". It recognised has a fan heater. It did not reliably recognise won't put it on. The weakness had been noticed in testing in November, logged, and scheduled for repair in the next release.

"And the next release?" said Hapgood gently.

"Version 2.1 was deployed in March. Version 1.9 has been withdrawn from service. It no longer runs anywhere."

"So the system that misread Mrs Sallis's message," said Hapgood, turning a little towards the coroner, "no longer exists."

"That's correct."

He sat down. I watched Riverlink's solicitor nod, very slightly, as a man nods when the band has struck up the tune he asked for.

I asked Dr Halloran only two questions. When the weakness was found in November, who decided that version 1.9 should go on running through the winter? She did not know; it would have been a product decision. And did Calloway's lease with Riverlink, which I had in my hand, say anything about who bore the cost of an error? It did. Clause 14. The cost of an error lay with the customer, Riverlink, "save where caused by a defect notified to the Supplier and unremedied". She had not seen the lease. Nor, I suspect, had she been meant to.

---

It was on the third morning, in closing submissions, that the coroner asked her question. Hapgood had finished. His submission came to this: that no human being in the chain had acted unreasonably; that the cause was a technical defect in a system now retired; that the appropriate conclusion was a narrative one which said so; and that lessons had been learned. He said lessons had been learned twice, with a sort of tenderness, as a man speaks of a dog that has been put down.

Mrs Arkwright took off her glasses and let them fall on their cord.

"Mr Coke," she said, "before you begin. Mr Hapgood says, in effect, that the system made the error. But I cannot find against a system, and I may not find against a person. I read classics at university, a very long time ago. The Athenians had a court for this, did they not? At the Prytaneion. Where they tried the axe. Perhaps that is what we are missing. I'd be interested in your view."

There are moments at the Bar when Providence hands you the brief you would have written for yourself. I put my unlit cigar back in my pocket, where it had no business being in the first place, and I gave her my view.

---

"Madam, they did. Demosthenes lists it, in the speech against Aristocrates, as the fourth of the Athenian homicide courts. If a man was killed by a stone, or a piece of wood or iron, falling on him, and nobody knew who had thrown it, but somebody had the thing, the thing was prosecuted at the Prytaneion. Aristotle says the king archon heard such cases with the tribal kings, and heard animals there too. If the stone was convicted, it was carried beyond the borders of Attica.

"But there was another trial at the Prytaneion, every year, and I think it is the one we have been sitting in. At the festival of Zeus Polieus an ox was brought to the altar on the Acropolis, and allowed to eat the barley offered there, and for that sacrilege it was killed. The priest who struck it threw down the axe and ran away. Pausanias says that the axe was then put on trial, as though they did not know the man who did the deed. In his account the axe was acquitted.

"Porphyry tells it better, and less kindly. In Porphyry the trial goes down a line. Those who had carried the water for whetting the blades blamed the men who whetted them. The whetters blamed the man who handed over the axe. He blamed the man who struck the blow. And the man who struck the blow blamed the knife. The knife could say nothing, and so it was found guilty, and cast into the sea."

I paused there, as one pauses for a jury, though there was no jury. The radiator ticked.

"Madam, for two days I have watched the water-carriers. Riverlink says the failure was at the human review stage. Calloway says it was in version 1.9. And version 1.9 has been taken out and thrown into the sea in March, and everyone has gone home with clean hands. The knife cannot be cross-examined. It is very convenient, in a witness, not to exist.

"My client has been spared that. He has merely been spoken to. But I ask you to notice where Riverlink stood him. They told you there was a human in the loop. There was. They had put him exactly where the car-makers put the crumple zone: at the front, to take the impact so that the rest of the vehicle comes through intact. An American scholar, Dr Madeleine Elish, wrote a paper about this in 2019, and called it the moral crumple zone. I commend it to the Chief Coroner's library. Eleven seconds a contact. Words behind a click. A process for anyone who read too much. That is not a safeguard, madam. It is a place to put the blame.

"So: do we need a Prytaneion? I say we already have one, and that you are presiding over it. This court is its last descendant in England. Until 1846, when a man was killed by a cart, or a horse, or a millwheel, it was the coroner's jury that valued the thing that killed him, and the value was forfeit as a deodand, deo dandum, to be given to God, and in practice to the Crown or the lord of the manor. Then the railways came. On Christmas Eve 1841 a train of the Great Western ran into a landslip at Sonning Cutting and eight passengers died, and the coroner's jury put a deodand of one thousand pounds on the train. The railway companies did not care for juries that valued their engines, and in 1846 Parliament abolished the deodand. That was the end of the English trial of the axe. It was abolished, you will notice, the moment the axe was owned by a company.

"I do not ask you to revive it. But if I did, I could tell you what to value the knife at. Clause 14, and the invoices Riverlink disclosed, give its price. Six pence. Mr Peploe's fan heater, at today's price of electricity, would have cost him about fifty pence an hour to run. He didn't run it. Hestia cost Riverlink six pence to decide that he would.

"There is one thing more about the Prytaneion, madam, that the textbooks pass over because it is not about law. It was where the city kept its common hearth. A fire burned there that was not allowed to go out, and when a colony was founded, the settlers carried fire from that hearth to light their own. The hearth was called hestia. The trial of the axe was held beside it. I think the Athenians knew perfectly well that an axe cannot murder anybody. The trial was a ceremony for getting the city's hands clean, and they performed it every year, in the open, and everybody knew it for what it was. What I fear is not a court that tries machines. It is a court that tries machines as though they did not know the man, and means it.

"So I ask you for two things. A narrative conclusion that tells the truth about how the system was built, in the words of the evidence: eleven seconds, a click, a weakness known in November and left running through the coldest weeks of the year. And a report to prevent future deaths, under regulation 28. Address it to someone who can receive it. The chief executive of Riverlink Homes has an office in Croydon. The managing director of Calloway Systems has one in Shoreditch. Both have letterboxes, and both, under the regulations, must answer you within fifty-six days. Version 2.1 has neither. Neither did version 1.9. That was, if I may say so, the whole of its attraction."

I sat down. Delia, who does not approve of speeches, passed me a peppermint, which is as close as she comes to applause.

---

Mrs Arkwright gave her conclusion at four. Mr Peploe died of hypothermia. The cold of his flat was the consequence of a heating failure whose repair was wrongly classified as non-urgent by an automated triage system, a system known to its supplier to misread messages of that kind; and the review of that classification took place under arrangements that allowed, on average, less than eleven seconds for each request and did not show the reviewer the tenant's words. No person was named. Section 10 was obeyed to the letter, and I have never been so glad of a statute's modesty. She would be writing, she said, to the chief executive of Riverlink Homes and to Calloway Systems Limited.

Mrs Sallis did not speak to me afterwards, nor to anyone. She sat with her coat on in the front row until the court had nearly emptied, and then she went out holding her handbag in front of her with both hands.

In the corridor Gary Tullett shook my hand for a long time, as the young do when they don't know what else to do with it. "They'll still sack me," he said.

"Very possibly. But they'll have to find someone else to say why."

Behind us Hapgood's junior had her phone to her ear and was speaking quietly, without urgency. "No, that's fine, nothing in it that touches the deployment. Two-point-one goes live in Lambeth on Monday."

I thought of the end of Porphyry's account, which I had not given the coroner, because it was not evidence of anything. When the knife had gone into the sea, the Athenians stuffed the dead ox's hide with straw, stood it on its feet, and yoked it to a plough.

I walked down Tennis Street towards the river in the half dark. It had begun to sleet. At the lights on Tooley Street a white van drew up beside me with the Riverlink kingfisher on its door and, under it in a cheerful blue, Hestia — here for your home, day and night. The lights changed. The van turned east, towards Rotherhithe, and I stood on the kerb with my collar up and watched its tail-lights go.
