From the Sunday Times bestselling author of Some Day I’ll Find You comes a taut and suspenseful thriller set in northern England’s Lake District where, beneath the inviting water of the lakes, danger and death are waiting.

The summer of 1976 was unprecedented in living memory. Days of blazing sunshine bled into weeks and months. In the Lake District, Cumbria’s mountains and valleys began to resemble a Grecian landscape. People swam and cooled off in delightfully tropic waters. But barely three feet below the surface, the temperature remained just a degree or so above freezing. As the summer blazed on, the drownings began…

What if someone wanted to take revenge? To remove an abusive, controlling partner from their life? When and where better to stage a murder and pass it off as an accidental drowning?
