Readers of mystery thrillers will find much to please them in this highly exciting story. It tells how Marjery Latimer living in a Bayswater boarding house was awakened one night by a scream. Slipping from her bed and crossing to the window she was in time to see a man hurrying down the street. The first of a series of crimes, which was to horrify the public and baffle the authorities had been committed! The mystery was further deepened by the strange behaviour of Marjory's employer who, in the apparent effort to be rid of her, told her of another and more lucrative position. Marjory accepted, but to her dismay recognised in her new employer the man she had seen hurrying away from the scene of the crime. Then a second murder was committed and the hue & cry reached fever pitch as the re-doubled efforts of the police failed to bring the guilty to justice.
