Following a harsh winter, the dam gates at Farris Lake have been badly damaged, and as summer approaches the lake must be drained for repairs.

Under the intense summer sun, the idyllic lake transforms into a barren wasteland – until the secrets that have long been buried beneath the surface are uncovered…

On both sides of the lakebed, new evidence relating to unsolved cold cases is discovered – the remains of a young man who went missing eight years ago, and the belongings of a girl who disappeared four years later.

Detective William Wisting is certain these crimes are linked. The lake has long hidden its secrets – but can Wisting now bring the truth to light?
