One or the Other — John McFetridge

This police procedural set in 1970s Montreal is “an enjoyable read . . . that immerses readers in a tumultuous period in Canadian history” (Publishers Weekly).
 
In the weeks before Montreal is to host the 1976 Summer Olympics, the police are bolstering security to prevent another catastrophe like the '72 games in Munich. But it isn't tight enough to stop nearly three million dollars being stolen in a bold daytime Brink's truck robbery.
 
As the high-profile heist continues to baffle the police, Constable Eddie Dougherty gets a chance to prove his worth as a detective on another case. He's assigned to assist in a Quebec suburb investigating the deaths of two teenagers returning from a rock concert across the Jacques Cartier Bridge. Were they mugged and thrown over the side? Or was it a murder-suicide? With tensions running high in the city and his career at stake, Dougherty is about to confront one of the most challenging cases of his life.
