Shadow of the Knife by Richard Ayre

Book 101 Review

A genius criminologist haunted by his past. A brilliant detective with everything stacked against him. A mysterious murderer that can’t be stopped.
It has been two years since Jack the Ripper stalked the streets of London. Two years in which the East End slowly returned to normality.
And then the killings start again.
When Detective Jonas Handy finds himself faced with a terrifying spate of new murders, he has nowhere to turn except Doctor Carter “Jigsaw” Jarman: a man whose knowledge of the criminal brain is unmatched in Victorian London.
