When a body identified as her own washes ashore near the Pointe au Père Lighthouse, it throws Evelyn Chambers's life into chaos. Professional diver Evie Chambers gave up working with the Underwater Retrieval Team when the last body she recovered hit too close to home. Now, she works as a private detective to fill her days and keep the nightmares at bay. The last thing she expects is to become a victim of one of her most frequently investigated crimes, identity theft. While that's problematic in itself, having the thief die mysteriously turns the theft of her identity into a tricky situation. The police inspector in charge of the case doesn't trust outsiders and warns her to stay out of police business. Not satisfied with that attitude, Evie goes to Rimouski, Quebec to discover the truth for herself. She intends to find out why the stranger stole her identity and nothing, especially not a crusty old inspector, will stop her. Alphonse Binette, the handsome Parks Canada employee who oversees the Empress of Ireland Museum piques her curiosity in more ways than one. In his spare time, Al runs a licensed dive company, one of the few allowed to go down to the wreck, and knows a lot more about the body found on the beach than she expected. Al offers to help her with her investigation, and while Evie is cautious, she accepts. There are strange things going on in Pointe au Père, starting with a break-in at the museum, rumors of people rising out of the water, strange lights, sounds, vanishing boats, roads that appear where they shouldn't, and a suspicious fire where another body is discovered. The police inspector is determined to solve the case without Evie's assistance or interference, but when circumstantial evidence makes Al the prime suspect in both the murder and the arson, it's up to Evie to discover the truth and clear Al's name before someone else dies.
