As Jack the Ripper's reign of terror in London comes to an end, a new era of depravity sets the stage for the first gripping mystery featuring the detectives of Scotland Yard's Murder Squad.

"If Charles Dickens isn't somewhere clapping his hands for this one, Wilkie Collins surely is."-The New York Times Book Review

Victorian London-a violent cesspool of squalid sin. The twelve detectives of Scotland Yard's Murder Squad are expected to solve the thousands of crimes committed in the city each month. Formed after the Metropolitan Police's spectacular failure in capturing Jack the Ripper, they suffer the brunt of public contempt. But no one can anticipate the brutal murder of one of their own...

A Scotland Yard Inspector has been found stuffed in a black steamer trunk at Euston Square Station, his eyes and mouth sewn shut. When Walter Day, the squad's new hire, is assigned to the case, he finds a strange ally in Dr. Bernard Kingsley, the Yard's first forensic pathologist. Their grim conclusion: this was not just a random, bizarre murder but in all probability, the first of twelve.

The squad itself it being targeted and the devious killer shows no signs of stopping. But Inspector Day has one more surprise, something even more shocking than the crimes: the murderer's motive.
