Thomas Norton, about to be killed, leaves an urgent recorded message for Charlie: Someone is out to destroy one of the Angels. Lab man Jarvis traces the call to Los Angeles Airport. Under the surveillance of hit man Jellek, Bosley and the girls find Norton's body in a parking lot phone booth. Norton is identified as a smalltime crook whom Charlie once did a favor. Kelly's houseguest Sally Miles moves to a hotel for safety's sake. John Gorman, boss of Jellek and Norton, slips into Sally's hotel and eavesdrops. Someone tries to run Sabrina's car off the road, and a mystery shot gives her a flat tire. John Gorman, listed in Norton's address book and on the TWA passenger list, proves to be an old cellmate of Norton's. Sabrina calls Sally at the hotel and learns that Kelly has gone home. But there is no answer at Kelly's house; she has been seized by Gorman. Gorman, real name Wilson Flicker, is Sally's fiancée. He fears that Kelly, who once helped send him to prison, will expose him as an embezzler who specializes in bilking young women. He will kill, if necessary, to conceal his secret.
