A beautiful French actress with concealed origins and a clandestine involvement with a group of anarchists is brutally murdered in London. Circumstances lead Scotland Yard to several suspects, including her wealthy American fiancé, a couple of the anarchists, and even a respected “Yard” detective. The search for the killer sets off an absorbing mystery with an interesting cast of characters and plot twists. Gordon Holmes is a pen-name of Louis Tracy (1863-1928), a British journalist and prolific writer of fiction. (Lee Smalley)
