It was the most incredible thing: a corpse driving an empty hansom cab through the foggy streets of a London evening. And it wasn't just any corpse but the body of a peer of the realm. This was sheer lunacy. Who on earth would want to unearth a decently buried old chap like Lord Augustus Fitzroy-Hammond? The doctor insisted that his death had been natural. But there was nothing natural about this as far as the police were concerned. Inspector Pitt was determined to reveal the truth, but even he was unprepared for the horrors of greed and exploitation that lay in store.
