Helena and Maia were good friends. "What happened?" I asked quietly.

"I'm not sure." Helena looked troubled. She had an idea- but she hated it.

I considered the situation. There was one possibility. Before my sister so briefly became interested in Petronius, she had an abortive friendship with another man. "Anacrites!"

Well, she had sunk low there.

Maia deserved better in life than the dice she had shaken out for herself. First as a young girl, she had opted to marry Famia. He may have looked amiable, and even stayed friends with her in his dozy way. Anyone connected with Maia would be stupid to give up on her. But Famia was a low proposition. He was a horse doctor for the Green charioteer faction and he drank continually. In his defence, he allowed Maia a free hand to run their household and bring up their children respectably which she could have done twice as well without his presence.

Maia was finally widowed and, newly unattached, she took on the traditional role of flighty piece. Her first foray was to adopt a male friend of stunning unsuitability, as widows like to do. Her chosen companion was Anacrites, the Chief Spy. Spies are never reliable lovers, due to their life of risk and their lying natures. Anacrites was also my sworn enemy. We had been forced into occasional shared work for the Emperor, yet I never forgot that Anacrites had once tried to have me killed. He was shifty, jealous, vicious and amoral. He had no sense of humour and no tact. He never knew when he should keep to himself. And I reckoned he took up with my sister just to get back at me.

A woman would have to be cracked to hitch up with a chief spy- any spy- but Maia always believed she could handle anything. Anacrites knew our family not only because he had worked with me; he had lodged with my mother. Ma thought he was perfect. I presumed my sister knew that our parent had a blind spot about men (well, dear Mother had married our father, for one thing). Maia also knew how I saw Anacrites. Anyone who looked that plausible had to be fake.
