The Vanishing Thief - The Dumnonia Mysteries 03

How could someone disappear from a castle on a cliff with stolen treasure, never being seen by the guards at its only entrance? The latest mystery infuriates the king, confuses the warriors protecting the castle and needs to be puzzled out by pagan priestess, Morvoren, and Christian deacon, Uxio. A friend of the queen's, who went missing on the night of the theft, seems to be mixed up in it. This puts the king and queen at odds and has them both demanding to know what happened, but how can an impossible theft be solved? Every answer leads to more questions and the subsequent appearance of a dead body doesn't help in the least.
