Historian Annie Kendall arrives at London's Bristol House on an assignment to research ancient artifacts from the Holy Land. She's desperate to escape her troubled past with the help of the shadowy employer who has hired her for an unusual, but well-paid, mission. So Annie is determined to ignore the strange manifestations in her flat--including the appearance of a ghostly Carthusian monk. When she crosses paths with Geoff Harris, a well-known TV journalist and a dead ringer for the strange apparition, they are called upon to crack an enigmatic code, still unbroken after five hundred years.

Widely acclaimed for her historical fiction, Beverly Swerling delivers an enchanting and epic tale of a historian and a monk half a millennium apart--and the unsolved mysteries of Tudor London that bring them together.
