The Sinister Course — Diane Weiner

When the dear friend of the town's beloved innkeeper is murdered, sleuthing couple Emily and Henry Fox don't hesitate to step in. Something's fishy regarding the property the victim recently purchased. The previous owner wants it back, the neighbors want it vacant, and the next of kin who stands to inherit the property is missing! Meanwhile, Henry and Emily's daughter, Maddy, may be in grave danger. Maddy's biological father has been prematurely released from prison due to a city-wide health crisis. When he shows up in Sugarbury Falls, Henry is determined to protect his daughter at any cost.
