A musical cold case has Cullen and Cobb back on the beat. On February 28, 1965, a young singer named Ellie Foster stepped into the alley behind The Depression, a Calgary folk club where she shared the bill with Joni Anderson, later to become famous as Joni Mitchell. During a cigarette break in the back alley, Ellie was forced into a car and the musicians with her were shot and killed. The investigation that followed turned up no sign of the kidnappers, and Ellie Foster was never seen again. Now, more than fifty years after the singer’s disappearance, Ellie’s granddaughter approaches Cullen and Cobb to try to find out what happened to her grandmother. The search for the truth about Ellie Foster takes the two investigators straight into the past. They find themselves investigating a failed political assassination and discover that there are those who will stop at nothing, even half a century later, to ensure that certain secrets remain untold.
