Friday (Jack Webb) and Smith (Ben Alexander) investigate when landlady Selma Bruttig (Isabelle Dwan) reports the disappearance of two of her tenants, a man and his wife. She suspects murder, but there is no physical evidence of foul play. It takes a howling dog to lead the detectives to a garden wherein a horrifying secret is hidden. This episode was adapted from the Dragnet radio broadcast of March 9, 1954 (in which, surprisingly, we never learn the murderer's motive). ~ Hal Erickson, Rovi
