My rating: 4 out of 5 stars
A recurring secondary character in Gabaldon's Outlander series, Lord John Grey is secretly homosexual--an important fact to know if you haven't read the series like myself--at a time in which it was "frowned" upon to say the least. This important secret affects how John interacts with all the other characters throughout this mystery in which English, Hanoverian, and Prussian soldiers and nobles seemingly deal with the supernatural.
In and around the town of Gundwitz, a succubus is believed to be attacking men-both civilian and military. John as the liaison officer between the England and various German allies and townsfolk finds himself in the middle of the investigation. Meanwhile he is in a weird love triangle between a Hanoverian officer and a young widowed Princess, who gets really interested in him after he helps her young son not be kidnapped by "a witch". Yet, it turns out that incident is connected to everything else going on that John has to deal with. As a mystery it keeps the reader guessing until the solution comes into focus, yet while John deals with this mystery he attempts to guess about a possible love connection as well.
