The case of the dangerous dowager

Perry Mason is retained by cigar-smoking, free-thinking, and hard-driving Matilda Benson to get IOUs totaling $7000 is gambling debts that her granddaughter Sylvia owes to two hardballs, crooked proprietors of The Horn of Plenty, who are willing to sell them to the highest bidder- which might end up being Sylvia’s cunning husband, who will stop at nothing prove Sylvia is an unfit mother, and should not be trusted with her daughters trust fund when they divorce. Matilda Benson hires Perry to get these IOU's by any means necessary, and after a successful tête-à-tête with the gambling hall’s two owners, he meets them on their turf but stumbles onto a body instead. He uses every legal trick in the book to keep Matilda, Sylvia, and himself out of trouble with the law!
