Ian Carreg, a charming detective with a career he loves, is coming to terms with the recent death of his wife and middle age. He's sent to apprehend a convicted felon, Jemma Henderson. She is a gifted surgeon with beauty to match and the daughter of a famous physicist - and a murderer. When he pursues her to Cymry Henge, something - or someone - knocks him out cold. He regains consciousness in a strange yet oddly familiar place - second-century Roman Britain. An encounter with three armed horsemen leads to an extended stay in the horsemen's village. Then the Roman cavalry arrives, and Ian and Jemma must fight to save their lives. They become Roman prisoners, and Ian starts to doubt his sanity. When their captors send them on a journey Ian finally accepts the truth - just in time to join with Jemma in foiling a conspiracy that could alter history.Michael Allen Dymmoch has served as president and secretary of the Midwest Chapter of Mystery Writers of America, and newsletter editor for the Chicagoland chapter of Sisters in Crime.
