Fire, Burn! - John Dickson Carr

Hurled back in time, a London police detective struggles to solve a nineteenth-century murder mystery in Golden Age master John Dickson Carr's thrilling mystery novel

A woman is killed in a well-lit corridor, dying before the eyes of three witnesses who, impossibly, detect no foul play. For more than a century, this baffling murder lies cold in the files of Scotland Yard until it is discovered by Detective-Superintendent John Cheviot, who yearns to apply modern scientific policing to the grisly old case. He is about to get his chance.

Taking a cab to Scotland Yard, Cheviot steps out in front of Old Scotland Yard and sees a beautiful woman beckoning him. Suddenly it is 1829 and Cheviot is a member of the newly organized London police force. He might now have an opportunity to solve the most puzzling murder in the Yard's history, but in a time before fingerprints and ballistic analysis, he will find police work to be far more baffling and brutal than he is used to.
