"Bullseye" was the first bonafide solo adventure for Honor Blackman's Cathy Gale, and clearly one of her best. A firearms firm is suspected of illegally supplying guns for African nations, so Steed purchases 20 percent of their stock and makes Cathy a major shareholder. Ronald Radd (later seen in "The Outside-In Man" and "Mission ... Highly Improbable") debuts as Henry Cade, whose every successful offer to buy shares in her company are foiled by the sudden deaths of the shareholders. Cathy easily carries the load while Steed handles things offscreen, and the whodunit aspects never fail to intrigue. The actors deliver strong characterizations, and director Peter Hammond occasionally dazzles with the camera, especially one dizzying back and forth encounter between Cathy and Cade, setting up the climactic showdown at the target range. The wonderful Bernard Kay is the shadowy figure in the background, who unfortunately, hasn't much to do (and never did another episode). Fred Ferris, as the Inspector who considers Cathy a suspect in the murders, also appeared in "Brief for Murder," while Judy Parfitt went on to do "The White Elephant," "Escape in Time," and "Whoever Shot Poor George Oblique Stroke XR40?" Previously, Mitzi Rogers did "Toy Trap," and John Frawley did "Mission to Montreal."
