The Father Hunt - Rex Stout

All pretty Amy Denovo wants to find the father she has never seen, but she can't afford Nero Wolfe's outlandish fees . . . or can she? Suddenly she's knocking on the oversized detective's door with a parcel full of bills in hand-and a quarter of a million hidden in her closet. It's all part of a nest egg left by her unknown father. But when Wolfe and his able assistant, Archie Goodwin, begin to trace the money to the man, they make a startling discovery: Amy's father murdered her mother-and now he may be after her.

"It is always a treat to read a Nero Wolfe mystery. The man has entered our folklore."-New York Times Book Review
