Let me identify suspects for myself, please,' I instructed.. Was there any information from the girl's aunt?'

She stayed in Olympia until there seemed nothing else she could do. Then she abandoned the tour and returned home. She was devastated when I finally discovered my daughter's fate.'

Can you put us in touch with the lady?'

Unfortunately no. She is abroad again.' My eyebrows shot up.. She enjoys travel. I believe she has gone to Alexandria.' Well, that's the trouble with holidays; every time you take one, you need another to recover. Still, it was three years since her niece died; Marcella Naevia was entitled to resume her life. People must have said Caesius should do the same; he looked tetchy.

While I noted down the aunt's movements, Helena took over.. So, Caesius. You were so dissatisfied with the official version of events, you went out to Olympia to see for yourself?'

At first I wasted a lot of time. I assumed the authorities would investigate and send me word.'

No news came?'

Silence. So it was almost a year later that I travelled there myself. I owed it to my child to discover what had happened to her.'

Of course. Especially if you have doubts.'

I have no doubt!' Caesius burst out.. Someone killed her! Then somebody – the killer, the tour arrangers, some other tour member, or the local people – covered up the crime. They all hoped to forget the incident. But I shall never let them forget!'

You went to Greece,' I intervened, calming him.. You spent a long time haranguing the authorities in Olympia. In the end, you yourself discovered human remains outside the town, with evidence that confirmed it was your daughter?'

The jewellery she wore every day.'

Where was the body?'

On a hillside. The Hill of Cronus, which overlooks the sanctuary of Zeus.' Now Caesius was struggling to sound reasonable, so I would believe him.. The locals claimed she must have wandered off, maybe on some romantic whim to watch the sunset – or sunrise – or listen for the gods in the night. When they were being most offensive, they said she was meeting a lover.'
