Ahead of us, the killer also struggled. He knew the ravine of old, yet found no easier way through it than we did. If paths had ever existed, harsh foliage had reclaimed them. Its prickly growth was impenetrable. The atmosphere, the heat, the smell, drained us. Being in a group, we just about kept up our spirits, and were closing the gap between us and our quarry. Nobilis was alone. He was on his own for ever now, and he knew it.

In the end he could go no further. With no way out, he turned on us. We never saw him coming but suddenly we heard him, as with a long, wild yell, he crashed out of hiding. With barely time to react, we bunched closer, bringing our swords up defensively. For an instant it did seem his intention was to break out past us. The ravine was too narrow, the tangled thicket too dense. His animal howl of defeat, despair and rage continued. We braced ourselves.

Nobilis flung himself straight at us. So this man, who had killed so many people with his own crude weapons, used us and our raised swords to kill himself.

Once we dragged out our blades and the corpse fell to the ground, we stood in shock. Silvius recovered first and rolled him over. We gathered round, to inspect the remains. We had to see, once, the man we knew to be the killer.

He looked younger than Probus and the twins. There were likenesses. We could see he belonged to the Claudii. He was bigger, more unkempt, over-heavy. Dead as he was, he lay staring at the sky in a way that made us shiver. Camillus Justinus, a man of refinement, stooped down quickly to pull the eyes shut with one thumb and forefinger.

Just before he did so, Quintus looked up at me. ‘That barman’s wife in the Transtiberina may have seen Nobilis. She said he had peculiar eyes.’ He spoke with the same throwaway manner Helena would use in company, tossing me something to think about, for discussion later. I said nothing, but I looked—then I drew the same conclusions.

We left the body there. We were exhausted. Dragging it back up the ravine would have finished us. If his siblings wanted to collect Nobilis for burial, let them.

‘Myself, I like to go to law,’ said Silvius, back in Antium. ‘A quick show trial, and a bloody execution. Deterrent to others. Suicide-by-cohort never works the same.’

Since the Urban was in a vengeful mood, he then let on that Claudius Probus was to remain in custody.

‘What happened to his get-out clause?’

‘Ah, Falco, I just remembered! I am not empowered to offer it. Immunity from prosecution is reserved to the Emperor—and he, I gather, never intervenes in criminal cases . . . So it’s thanks for the help, Probus—but tough luck!’
