Harry Fielding has had enough of the low life. He's through with being an understrapper for MI5. It's time to make a new start. He'll spend more time with his widowed father, Cecil. He'll look into that job he's heard about-a concierge/handyman for a small hotel. But Harry's fishing holiday with his father is interrupted by his old friend Alfie, the crooked policeman. Alfie is in trouble. Actually, Alfie is trouble, but Harry is not one to abandon a friend, especially since Alfie's wife, Ruth-all long fingers and perfect belly-is also anxious to see him again. As it turns out, Alfie has been suspended from the police force but has lined up a private investigation job that calls for Harry's expertise. But once on the case, Harry begins to wonder just what he is expected to do.
