Murder Is My Business is a 1946 American action film directed by Sam Newfield and written by Fred Myton.
The film stars Hugh Beaumont, Cheryl Walker, Lyle Talbot, George Meeker, Pierre Watkin, and Richard Keene.
He has hatched an insurance fraud scheme in which the actor would break in and find $1000 in an empty jewelry case in his wife's bedroom.
But Carl Meldrum, an ex-con gigolo dating Dorothy, just happened to be present and witness the actual murder.
From the beginning Shayne has suspected Ramsey—his work was assembling the proof—and at the end he is able to conclusively show the police who the actual innocent and guilty parties are.
