The Rich and the Damned — Richard Himmel

Lawyer Johnny Maguire is caught in the middle when a wealthy industrialist dies and leaves him in charge of executing the inheritance... which his dead client's four children are desperate to grab. The children include the industrial's two daughters, one of whom has shared Johnny's bed and another who would like to. Meanwhile, a mobster is eager to take-over the dead man's business...even if it means killing.
