The Roman Mysteries Book 15: The Scribes from Alexandria

A desperate quest begins in the port of Alexandria: site of the great lighthouse, the famous Library, and the tomb of Alexander the Great. Codes, riddles, anagrams and hieroglyphics lead the young detectives down the river Nile to pyramids and sphinxes, temples and tombs, crocodiles and hippos. But what lies at the end of the journey? Treasure? Or death?
