Mr. Stormcroft (Leslie Perrins) visits Blake after his father was murdered in their West End mansion, where many female guests are staying. His father was shot in his library when most guests were in the drawing room. A search did not turn up a gun or revolver. Arriving at the library, Tinker discovers a piece of silken cloth stuck in a corner of the chair, and Blake notices scratch marks on the desk. The assailant must have been a woman! Blake breaks into the house several days later to examine the women's wardrobe, where he finds a dress that matches the cloth. Returning to the library, he discovers that Stormcroft's father, an English secret agent, had a secret drawer in his desk. He also finds the gun which looks like a walking stick. Just as he begins to call the police, the villainess, Valerie Simpson (Marjorie Hume), renders him unconscious with a smash on the head, but her escape is thwarted by Tinker and the policemen who arrive to check on Blake. Blake wakes up and tells Mrs. Stormcroft that Valerie is not the daughter of an old friend, but a Soviet agent named Nadia Petrowskaya. He has discovered a letter (conveniently written in English) addressed to "Sovian [sic] Headquarters" in her locked box. She shot the old man when the latter refused to give her an important document.
