The Bigger They Come: A Cool and Lam Mystery

Bertha Cool is the gruff, tough-talking, corpulent head of her private detective agency, opened after the death of her husband; Donald Lam is her meek, slight, and nervy new hire, who makes up for a lack of boldness with brilliant deductive work. The duo couldn't be any more dissimilar but, with their skills combined, they are an unstoppable force when it comes to solving crimes, as evidenced by their over two dozen successes in the long-running series penned by Perry Mason creator Erle Stanley Gardner.
