Alexandria

'I came fully equipped with the old prejudice that anything to do with Egypt involved corruption and deceit.'

AD 77. Egypt was the destination of choice for Roman tourists, being home to not one but two Wonders of the Ancient World, a Centre of Culture, and people with exotic habits.
Unfortunately, when Marcus Didius Falco pays a visit he discovers it's also a hotbed of schemers and murderers. When the Head Librarian dies in suspicious circumstances, the Roman authorities are only too happy to dump the case on one of the Empire's most celebrated investigators - all adding up to a typical Falco family vacation.
