A Body Surrounded by Water — Eric Wright

Although still the charming maritime province depicted in the Anne of Green Gables books, Prince Edward Island was no longer as tranquil. Greed, jealousy and rage had made it a setting for crime. Robbed were a dozen vacationers' cottages. Missing was a rare antique. Murdered was a local historian. And on the scene was off-duty Toronto homicide detective Inspector Charlie Salter.

Salter, on the island for a holiday with his family, was caught in a tug-of-war between in-laws looking for favors and female houseguests looking for love. Since Salter much preferred looking for suspects, he found a mysterious fish man, a churlish chicken man, and a weasel of an art dealer. But would he see the fox in a henhouse so close to home...and a clever killer about to strike again...?
