Her father had left on a planned trip some months before and she has had no contact with him. Nick isn t all that keen on resuming his former profession but egged-on by wife Nora, who thinks this all very exciting, he agrees to help out. He solves the case, announcing the identity of the killer at a dinner party for all of the suspects.
