The latest entry in the popular Matthew Corbett series, which began with Speaks the Nightbird and continued in The Queen of Bedlam, Mister Slaughter opens in the emerging metropolis of New York City in 1702, and proceeds to take both Matthew and the reader on an unforgettable journey of horror, violence, and personal discovery. The journey begins when Matthew, now an apprentice "problem solver" for the London-based Herrald Agency, accepts an unusual and hazardous commission. Together with his colleague, Hudson Greathouse, he agrees to escort the notorious mass murderer Tyranthus Slaughter from an asylum outside Philadelphia to the docks of New York. Along the way, Slaughter makes his captors a surprising - and extremely tempting - offer.
