The Better Bargain (1956)

The Better Bargain (1956) Louis Koster is a middle-aged mobster, now running a more-or-less legitimate business and enjoying a beautiful young wife. That is, until he suspects his wife of having an affair. A mousy little private eye confirms it. Now the only thing Louis "The King" Koster has left to do is hire Harry Silver. Silver is the best hitman in the business, but his price may come too high.
