I stared at the faint groove where it seemed Sosia’s stylus had erased a further name. My poor Sosia had been bound in law by ties that were not mine. Had she stood here now, fixing me with those great eager eyes that I remembered so vividly, I would have had to maintain her silence with her to the end. But she was long gone. And I still wanted bitterly to avenge her death.

There was one more person involved in this case: somebody so adept at shrinking out of view that I had almost deliberately ignored the obvious link. I thanked Lenia, grasped the ingot in my arms, and struggled with it upstairs to my room. Soon, wearing my best toga, the one that belonged to Festus, I came down again and went out to do what was necessary on Palatine Hill.

LIII

By the time I clambered up to the Palace, I felt so hysterical I expected the Praetorians to arrest me on sight. It was comforting to find that the Emperor’s Guards could apparently distinguish a true assassin from a hot but honest man. When I begged to see Titus I was passed in through officials of increasing refinement until a tall secretary, who gave the impression he would not flutter one long handsome eyelash if his mother-in-law caught him buggering the butcher in her backyard, listened and then propped me on a stool with my toga piled neatly in my lap while he walked away into an inner room.

Titus came out.

He made a magnificent sight. He had assumed his full military uniform as commander in chief in Judaea and a confident mood to match. He wore an ornamented breastplate, its torso moulded to heroic proportions, a richly dyed, completely circular purple cloak, and a tunic frogged on every edge with rigid palm leaf braid. Anything he lacked in height to carry this off, he made up in a muscular build. He was ready to go to the Temple of Isis, where he would spend the night solemnly with his father and his brother, before they entered the city tomorrow as victorious Roman generals bringing home their captives and glittering spoils.

Doubt now assailed me. My client had dressed as if to model for the formal statues that would gild his reputation for several thousand years. I did not believe in the power of ceremonial, but I knew that I had come on the wrong day.

I stood up. I handed Titus Sosia’s writing tablet, feeling the firm grip of his hand as he took it from me. He glanced in pinched silence at Domitian’s name, then ran his eye down the rest.

“Thank you, Falco. This is useful, but nothing new…” His eyes seemed remote, his mind half-given to the honours of tomorrow. Even so, he grasped my own hectic excitement in the end. “What—do you believe it is?”

I pointed out the gap.
