The Mystery of Schroon Lake Inn by K.B. Owen

Missing jewels...a haunted inn...a long-held secret...

Penelope Hamilton Wynch, one of the few female operatives employed at the Pinkerton Agency in 1886, is sent to the Adirondacks to investigate the mysterious happenings at Schroon Lake Inn, newly renovated to cater to New York City's upper crust on summer holiday. Rumors of ghosts are bad enough, but when expensive jewelry disappears, the owner's livelihood is at stake. A woman's touch is needed.

Pen's boss, William Pinkerton, thinks he has given her the perfect cover. She is to play the part of an eccentric spirit medium, eager to experience the purported ghostly manifestations. Unfortunately, her cover will not remain intact for long, and there are those behind the scenes who are desperate to keep the secrets of Schroon Lake Inn from coming to light. Will Pen's discoveries prove fatal? She would have to be truly clairvoyant to know...
