Third of the six episodes featuring nightclub singer Venus Smith (Julie Stevens), again an improvement on its predecessor. In demonstrating his magic box, a shady magician (Ian Curry) makes his female assistant disappear, then reappear, murdered by a fatal gunshot. Curiously, when her replacement (April Olrich) meets the same fate, the magician escapes suspicion! Steed brings Venus Smith into the picture, performing at the same nightclub where the murders occurred (two songs this time), and she's more helpful this time around, hearing voices from inside the magic box, and visiting an old friend (Jane Barratt) whose wheelchair-bound father, General Sutherland (Maurice Hedley), holds the key to the solution (NATO security leaks). Steed goes undercover in two disguises, one a masseur for the ailing General, wisely ducking out when Venus shows up (she blew his cover in "The Removal Men"), and later as a hypochondriac millionaire visiting Dr. Gallam (Edgar Wreford), the General's less than inspiring physician. Steed and Venus finally work well as a team, but had only three more together; next up for Venus would be "School for Traitors."
