I didn't need to be an informer to know we were stuck. When a four-year-old girl reckons she has detected something nasty, you just give in and look for it. My little niece would not go near the bath house until we proved there was nothing horrible in the caldarium. The more we scoffed and told her the hot room was only smelly because of its new plaster, the more Rhea screamed hysterically at bath time. There was nothing visible, and the rest of us tried to ignore it. But the child's insistence unsettled everyone.

There was a faint odour. If I tried sniffing it out, I lost it. When I decided there had been nothing, straight away I smelled it again.

At least Helena and I were able to go home to our own new house. My sister Maia and her children had to stay on there on the Janiculan Hill, in the home that was supposed to be their refuge from trouble, living with that other kind of trouble, Pa. My father, Geminus, and I were in the throes of a house-swap. While I tried to organise decorators to renovate his faded old lair on the bank of the Tiber, he took over the spread on which I had already worked for months, where all that remained for completion was the new bath house.

The Janiculan house had a highly desirable location if you worked on the north side of Rome. It suited Pa, with his auction house and antiques business in the Saepta Julia by the Pantheon. My own work required free access to all parts of the city. I was an informer, serving private clients whose cases could take me anywhere. However much I wanted to move out and across the river, I needed to live close to the action. Sadly, this sensible thought had only struck Helena and me after we had bought the new house.

By chance, father's long-term companion, Flora, then died.
