It is a most incredible sight: a corpse sitting at the reins of a hansom cab and not just any corpse, but the body of a peer of the realm. To Inspector Thomas Pitt and his wife, Charlotte, this macabre apparition seems like sheer lunacy. Who would ever want to exhume a decently buried old chap like Lord Augustus Fitzroy Hammond?A doctor insists that Lord Augustus s death was natural. But as far as the police are concerned, there s certainly nothing natural about any of this gristly aftermath. Inspector Pitt is determined to unearth the truth even if the digging puts his own life at perilous risk.
