When their parents are killed in a fire, Titus Adams and his younger sister Hannah are left to fend for themselves in the cruel and squalid slums of Victorian London. Taking shelter with his friend and saviour, Inspector Pilbury, Titus should feel safe.
But though the inspector has just caught and hung a notorious child-murderer, the murders haven’t stopped. Now everyone is a suspect, even the inspector himself, and unless Titus can find a way to end the killings, he will lose all that is dear to him. But as the killer closes in, Titus finds he is running out of time to avoid a catastrophe close to home. For this evil cannot be contained, even by death.
