Victorian London is a cesspool of crime, and Scotland Yard has only twelve detectives - known as "The Murder Squad"-to investigate countless murders every month. Created after the Metropolitan Police"s spectacular failure to capture Jack the Ripper, The Murder Squad suffers rampant public contempt. They have failed their citizens. But no one can anticipate the brutal murder of one of their own... one of the twelve... When Walter Day, the squad"s newest hire, is assigned the case of the murdered detective, he finds a strange ally in the Yard"s first forensic pathologist, Dr. Bernard Kingsley. Together they track the killer, who clearly is not finished with The Murder Squad... but why?
