Whitechapel, November 1988: Jack the Ripper is committing his last known act of butchery in the one-room hovel occupied by the luckless harlot, Mary Kelly. And beneath the bed on which the fiend is cruelly and cheerfully eviscerating his victim cowers a fifteen-year-old boy...

This is just the start of the extraordinary adventures of Trevor Bentley, a boy who embarked on an errand of mercy and ran into the most notorious serial killer in criminal history, a boy who became a man as he travelled on a quest of vengenance across a wild and untamed continent - a boy who brought the horrors of Jack the Ripper to the New World.
