Secret Whistler

 

 (imdb)

THE SECRET OF THE WHISTLER-1946-After the usual intro, a woman (Mary Currier) buys a headstone for herself (from Byron Foulger). Her husband Ralph Harrison (Richard Dix) is called away from a party he's throwing because his wife, Edith has a heart attack. He meets a model Kay (Leslie Brooks) and begins to romance her while waiting for his wife to die. Somehow, his wife gets better and overhears Harrison telling Kay how much he loves her. Edith throws him out but he returns at night and switches her meds with poison. She dies and he marries Kay. Everyone suspects him of murder but Kay finds the old wife's diary that has an entry that seems to clear Ralph. Both wind up dead and the Whistler keeps whistling. John Hamilton and Arthur Space have uncredited roles. 

This is another weird entry into the series (the sixth installment), this time directed by George Sherman (THE LADY AND THE MONSTER (1944)). Star Dix would make one more film in the series, which be his last film appearance as he died in 1949 at age 56. His death may have been hastened by alcoholism.
