Little Lazarus

DCI Vera Stanhope rescues a young boy from a freezing pond after he escapes from a violent attack which left his mother dead. As Vera and her team investigate what happened to the child, they unravel a web of deadly secrets and discover a murderous sequence of events set in motion by power, money and a mother's love. Although she is usually awkward and uninterested around children, Vera finds a kindred spirit in the boy, and begins to realise that the key to the investigation may lie hidden in his memory
