‘We asked ourselves what you would do, Marcus—then we broke the lock.’ Justinus spoke as if he had brought along a crowbar specially. ‘The spy can blame his fancy caterers. They are crawling everywhere.’ That fitted my fancy that Laeta was paying them to observe.

‘And was the “art” collection revolting?’ Helena asked. The lads assured her they were shocked. However, Justinus reckoned there were fewer pieces than when he stayed here last winter; Anacrites may have felt alarmed that other people knew about his filthy gallery so he had sold the most sinister pieces. A spy needs to avoid scandal. Besides, as I knew from Pa’s business, he would have made a killing from any of the private pornography collectors.

We returned to the dining room, all in a jolly foursome, so Anacrites might think we had been together all the time. I had not yet decided whether to tell Albia about us eavesdropping. She was now staring at the tumblers’ pratfalls, as if planning to run away to join them.

Claudia looked weary after being left alone to cope with Hosidia. I thought Hosidia brightened, as she watched Justinus sprawl back on his couch opposite her. Could his easy manners and good looks be attracting yet another young woman who really belonged to his stodgier brother? Claudia had once been betrothed to Aulus, but she dumped him—which her new sister-in-law had probably realised . . . But Hosidia would need some nerve to flirt with Quintus. If threatened, the once-shy Claudia Rufina fought for her rights with Hispanic bravura. In fact, being the senior bride in the Camillus family seemed to have fired up her confidence. Helena and I liked her; she was tougher than she looked.

Hey ho, I had convinced myself the Camillus family were about to enact a Greek tragedy . . .

Anacrites’ evening was starting to deteriorate. Dessert was the least impressive course he provided. It consisted of browned fruit and lacklustre pastries. I reckoned Anacrites had got this far in the caterer’s estimate then drew a line through any extras. He had a frugal streak. When I worked with him, it had always been me who went out for honeycakes to break the monotony.

While we toyed with grapes, Minas reappeared. He boomed that he had seen one of the chefs stealing a picture. Anacrites now seemed too deflated to deal with it. I jerked my head at the Camillus brothers. He was a host to avoid, but we were guests with manners. The lads needed no further telling. We three, tailed by the dispirited spy, marched to the kitchen to investigate.
