A serial killer is on the loose, slashing women and threatening Lt. Levinson's job! A good, serious cops and robbers story. Dick Powell sings, "Cruising Down The River" after the story. The same script used on the program on April 12, 1950. + When Lynnette Knight quits her job as a café photographer she is surprised at the unprovoked attempts on her life. She goes to Richard Diamond but leaves, as she cannot afford his $100 a day fee. But when Diamond receives a call threatening him not to take the job, he takes it… Levinson contacts Dick Powell to help him with a case. Someone is killing women in a brutal way and Levinson has to solve the case by next week or his job is on the line. This is the third killing like this in three weeks. Virginia Gregg is credited as Virginia Del Valle, her married name to Jamie Del Valle.
