Murder at Lost Dog Lake

2004 EPPIE finalist for best mystery.
Leanne Aimes, ex-cop, bitter single mother, private investigator, really needs a vacation. And the wilderness of Algonquin Park seems like just the place where she can relax and forget her troubles. A guided canoe trip is exactly what she needs. But it isn't long before her companions begin fighting amongst themselves. When a storm of unprecedented ferocity descends, the group is trapped on a remote island in the center of Lost Dog Lake. And Leanne comes to realize that someone in their small group is a murderer.
"A delightful read with a twist ending. A story that will hold your interest and one with lots of surprises. … the reader feels like they are a third party in a two-man canoe. All you need is an oar." Anne K. Edwards, Blether Book Reviews.
