October, 1987: As a hurricane sweeps through Britain, a man's body slowly rots, locked inside an old water tower in west London. He carries no identification and fits no missing persons' description. His corpse is never claimed. October, 2013: The month of the great storm of St Jude. A man dies beneath a late night Piccadilly line train. His brother insists he was murdered, but Jack, a train driver, is sure it was suicide.
