This is the last Scott Egerton mystery, and a counterpart to The Murder of Mrs. Davenport (1928). The accused and the victim in both books have the same names and a similar relationship. In Davenport, Denis Brinsley was arrested for the murder of his former mistress Helen Davenport, an obstacle to his marriage; in this case, Denis Paget is arrested for the murder of his estranged wife Helen, an obstacle to his marriage. “Be bloody, bold, and resolute” was the advice of the second apparition to Macbeth, and none better was ever given to a murderer. Had the person responsible for the death of Helen Paget followed it, an innocent man would have been hanged; but a passion for safety brought the real culprit to the gallows. Mrs. Paget was found shot dead in a private room of the Apsley Hotel, London. Helen Paget is found shot dead in a private room of the Apsley Hotel in London. Strong suspicion pointed to Denis Paget, the husband of the dead woman. Her murderer has developed a very complex plot to commit the killing without being caught, but he is too clever for his own good. The story develops into an enthralling mystery that will grip and fascinate the reader.
