Penny Nichols and the Knob Hill Mystery

A resourceful young girl accompanies her detective father to a rented cottage at Knob Hill and becomes drawn into a local mystery involving the reclusive Herman Crocker, his nephew and household members. Strange visits, hidden letters, a lost handkerchief, attic searches and a toy lantern provide a chain of clues that the pair and allies follow. A cantankerous housekeeper and the boy Michael supply inside information, leading to overheard conversations, identities examined, and a revelation about an alias that reshapes the case. The tone blends domestic detail with puzzle-solving and steady, clue-driven discovery.
