My father had been in possession of the murder weapon.
Which meant that the main suspect for killing Censorinus would now appear to be Didius Geminus.

It was a wild idea. Those are the ones that always seem the most believable once they strike you.
This was one thing I could not say to Helena. Not wanting to let her see my face, I stepped on to the balcony threshold. Ten minutes ago, he had been here, joking with the two of us, more friendly than he and I had ever been. Now I knew this.
He could have lost that knife, or even thrown it away, a long time ago. I did not believe he had. Pa was famous for collecting cutlery. When he lived with us, the decreed system was that every day he was given a knife in his lunch-basket; he usually pinched the daily knife. It was one of the irritating habits by which he made his presence felt. He was always in trouble about it, one of the endless wrangles that colour family life. Sometimes he needed a sharp blade to prod a suspect piece of furniture, testing for worm. Sometimes he had to swipe through the cords tied around a bale of new stock. Sometimes he palmed an apple from a fruit stall in passing, then wanted to cut slices as he walked. We children bought him a fruit-knife for a Saturnalia present once; he just hung it on the wall of his office, and went on exasperating Mother by filching the picnic tools.
He must still do it. I would bet he was driving the redhead to distraction with the same little game-still on purpose, probably. And the day Censorinus died, maybe the knife in his pouch had been that old one.
So my father could have killed the soldier. Why? I could guess: Festus again. Rightly or wrongly, Geminus must have been trying to protect his precious boy.
I was still standing there, lost in desperate thoughts, when we had another visitor. It was so close to my father's departure, and Geminus was so much on my mind, that when I heard feet on the stairs I thought it must be him again, coming back for a forgotten cloak or hat.
They were old feet, but they belonged to someone lighter and more fragile than my hefty pa. I had just worked that out, with great relief, when the new arrival staggered in. Out of context, it took me a moment to recognise his troubled voice as he asked for me. As I came in from the balcony I saw Helena, who had been full of concern for the old man, grow suddenly still as she noticed my own frowning face. The light I had meant to attend to was flaming up madly; she strode across and blew it out.
'Oh it's Apollonius! Helena Justina, this is the man I was telling you about the other day; my old teacher. You look terrible, Apollonius. Whatever's wrong?'
'I'm not sure,' he gasped. It was a bad day for elderly folk at Fountain Court. First my father had arrived whey-faced and coughing. Now the six flights of stairs had nearly finished Apollonius as well. 'Can you come, Marcus Didius?'
'Get your breath! Come where?'
'Flora's. Something has happened at the caupona; I am sure of it. I sent a message to Petronius Longus, but he hasn't appeared, so I thought you might advise me what to do. You know about crises-'
Oh I knew about those! I was up to my neck in them.
Helena had already fetched my cloak from the bedroom. She stood holding it, staring hard at me but keeping her questions to herself.
'Stay calm, old friend.' I felt a strange, deep, gentle care for other people who were in trouble. 'Tell me what has disturbed you.'
'The place has been shuttered since just after lunch-time-' Flora's never closed in the afternoon. So long as there was a chance of extracting a copper from the public for a lukewarm stuffed vine leaf, Flora's never closed at all. 'There is no sign of life. The cat is scratching at the door, crying horribly. People have been beating on the shutters, then just walking away.' Apollonius himself probably had nowhere else to go. If he found the caupona unexpectedly closed he would just sit outside on his barrel hopefully. 'Oh please come, if you can, young Marcus. I feel something is dreadfully wrong at that place!'
I kissed Helena, grabbed my cloak and went with him. The old man could only go slowly, so when Helena decided not to be left out, she soon caught up with us.
We saw Petronius arrive at Flora's just ahead of us. I was glad of it, although I would have gone in on my own otherwise. But Apollonius was not alert to the sensitivities. I was still under suspicion for what had happened to Censorinus. If there was some new upset at the scene of his murder, it was better to have official company.
The caupona was as the old man had described. Both huge shutters had been drawn across the wide entrances in front of the counters; both were securely locked from inside. It looked as I had rarely seen it except at the dead of night. Standing in the street, Petronius and I tossed up pebbles at the two small windows in the upper rooms, but nobody responded.
Stringy was gnawing at one doorpost miserably. He rushed up to us, hoping we might give him some dinner. A caupona cat does not expect to find himself hungry; he was thoroughly indignant. Petronius picked him up and fussed him while he stared at the locked building thoughtfully.
Across the street at the Valerian there were more customers than usual. People, some of whom would normally have been wasting a few hours at Flora's, turned on their elbows to watch us, while eagerly discussing the unusual activity.
We told Apollonius to wait outside. He sat down on his barrel; Helena stopped with him. Petronius gave her the cat, but she put it down fairly swiftly. Even though the poor girl had fallen for an informer, she did have some principles.
Petro and I walked round to the back alley. There was the usual stink of kitchen rubbish; the usual seedy atmosphere. The stable door was locked-the first time I had ever seen that. It was of flimsy construction; the lower portion was weaker and gave way to a hard shove from Petronius. He reached in and fiddled with the bolts on the upper half, eventually giving up and simply ducking underneath. I followed. We emerged inside the kitchen area. Everywhere was completely still.
We stood, trying to see in the dark. We recognised that silence. We knew what we were looking for. Petronius always carried a tinder-box; after several attempts he struck sparks, then managed to find a lamp to light.
As he held up the little lamp he was standing ahead of me, his bulk blocking my view. His shadow, that great head and the raised arm, sprang up to the side of me, flickering alarmingly on the rough caupona wall.
'Oh shit, he's dead!'
I assumed it was another murder. Still locked in my own preoccupations, I thought drably, Geminus must have come here and killed the waiter just before he turned up at Fountain Court so full of concern for us, so full of laughter and fun:
But I was wrong. I had hardly begun to feel angry with my father when Petronius Longus moved aside for me.
I noticed another shadow. By the single flame of the feeble lamp, its slow motion attracted attention as a long, dark, slanted shape turned slightly with some changing air current.
In the well of the stairs was Epimandos. He had hanged himself.

Petronius had the longer reach. He cut the body down, not even needing the stool Epimandos had used. We were far too late; the corpse was cold. We carried him into the deep dark of the interior, and laid him on a counter. I fetched the thin blanket from his bed and covered him. Petronius unlocked and partly pushed open a shutter. He called in the others.
