On Leap Year Day in 1964 an attractive teenager called Carole Jeffries was strangled in a Liverpool park. The killing caused a sensation: Carole came from a wealthy family and her pop musician boyfriend was a leading exponent of the Mersey Sound. When a neighbour confessed to the crime, the case was closed.

Now, more than thirty years later, Ernest Miller, an amateur criminologist, seeks to persuade lawyer Harry Devlin that the true culprit escaped scot free.

Although he suspects Miller's motives, Harry has a thirst for justice and begins to delve into the past. But when another death occurs, it becomes clear that someone wants old secrets to remain buried. At any price.
