The war may be over, but for Molly life is still in turmoil. Uprooted from London after the death of her mother, Molly, her father and younger brother Jimmy are starting again in a quiet village in the countryside of Colchester. As summer sets in, the heat is almost as oppressive as the village gossip. Molly dreams of becoming a journalist, finding a voice in the world, but most of the time must act as Jimmy's carer. At just ten years old he is Molly's shadow, following her around the village as she falls under the spell of local boy Kit. Kit is clever, funny and a natural-born rebel. Rowing on the waters of the lake with him becomes Molly's escape from domestic duty. But there is something Kit is not telling Molly.
As the village gossip starts building up with whispers against Molly's father over missing charity funds, everything Molly thought she knew is turned upside down. And on one stormy night, when she sneaks out of the house to try to put things right, Jimmy vanishes. Never to be seen again.
Decades later, Molly is an elderly woman in a care home, still haunted by the disappearance of her brother. When two police officers arrive to say that the remains of a body have been found at the bottom of the lake, it seems like Molly will at long last have her answer . . .
