August, 1976. The longest, hottest summer anyone could remember. No wonder families flocked to the golden beaches of East Anglia, where there was a breeze and where the chill of the North Sea was, for once, a welcome relief. If you were a child, it was the best summer ever...

Eve is already feeling under siege when the Norfolk police appear at her door. They've found new evidence in the disappearance of a father and son from a beach in a night storm fifty years ago. Blood on a t-shirt, and a connection to a seaside chalet called Spindrift where she and her sister Jude spent the summer, just before their mother put them into care and vanished from their lives.

Now Eve and her sister are going back to Spindrift, where everything went wrong, to see if the children they used to be can give some answers to the women they've become. What happened there, when the tension in their little house simmered as the thermometer rose, and more than one child was lost?
