Safe Harbour by Mike Martin

Safe Harbour: The Sgt. Windflower Mystery Series Book 10 

Sgt. Windflower is happy living on the east coast, in St. John’s, Newfoundland, spending time with old friends and new, while on a special assignment. But he’s decidedly not as happy navigating the big city and dealing with a difficult boss. When several girls go missing—one of whom is from his home town of Grand Bank—Windflower is pulled into the underbelly of the city and all its dark secrets. Can he track down the truth and stop whoever is making these girls disappear or is he destined to keep chasing the fog in the harbour?
