The perfect summer read’ - Clare Mackintosh, author of the bestselling I LET YOU GO From the author of the bestselling Some Day I’ll Find You comes a novel of dark suspense set in the 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 in delightfully tropic waters to cool off. 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?
