A body in the bath house - Lindsey Davis

The thirteenth whodunnit featuring Marcus Didius Falco
ancient Rome's Philip Marlowe
set against the very real backdrop of the Roman Palace at Fishbourne in Britain.

Falco and Helena have escaped Helena's expensive mistake on the Janiculan Hill and house-swapped with Falco's father. But they've left behind a nasty surprise. There's a corpse in the newly completed bathhouse and the contractors, Gloccus and Cotta, have fled to Britain. As it happens, Britain is currently Falco's best employment opportunity. Frontinus, Governor of the Isle, wants Falco to sort out some problems he has with a huge Imperial building project on the south coast. Is it there that Gloccus and Cotta have fled? With his burgeoning family in tow, Falco sets out to the land he swore he would never visit again, not knowing that a string of murders and building site politics await him.
