This is a comedy by Pat Cook. Christmastime rolls around, and our down-and-out gumshoe is short of cash as usual. He's down to walking dogs for a few bucks when Harrigan's department store has its payroll stolen. And who you gonna call? Loretta Mondello, the store manager, has complete faith in Harry pulling this one off. After all, she's his mother! Not only is the payroll missing, but crime of all crimes, somebody kidnapped Santa Claus!
