A cheaper edition of David Dresser's Parole Chief (Viking-1950) which applies little social understanding or vision to what is primarily a case history chronicle of characters met up with in the professional pursuit of duty. From his first ""tail"" assignment as parole officer, Berson (no better spoken than his charges) introduces a mixed lot of criminals -- absconders and extortionists; hoods and hold-up men; a spy and a bookie; the McCanns- brothers and safecrackers -- and as tricky a combination as any they broke. Herman Muller, the mild man who killed his wife -- and then came out of prison fourteen years later to murder the lover who had defiled her; a Negro, framed with a rape charge; an unfrocked clergyman; etc. etc. A criminal close-up which derives from experience and which is set down in the vernacular of the company kept up with. You too can be vigilant.
