Superintendent Frank Castle Froest was a British detective and crime writer.Froest was described by a journalist as being "...short, thick-set, full-faced, Mr.Froest in uniform looked more like a Prussian field-marshal than anything else. Out of uniform (which he generally was) he was always immaculate in silk hat, patent leather boots, and carrying a carefully rolled umbrella." Called 'the man with iron hands', Froest was incredibly strong, and could tear a pack of cards in half and snap a sixpence 'like a biscuit'.
