Lord Peter begins his hobby of investigation by recovering "The Attenbury Emeralds" in 1921. At the beginning of "Whose Body?" there appears the unpleasant Inspector Sugg, who is extremely hostile to Wimsey and tries to exclude him from the investigation (reminiscent of the relations between Sherlock Holmes and Inspector Lestrade). However, Wimsey is able to bypass Sugg through his friendship with Scotland Yard detective Charles Parker, a sergeant in 1921. At the end of "Whose Body?", Wimsey generously allows Sugg to take completely undeserved credit for the solution; the grateful Sugg cannot go on with his hostility to Wimsey. In later books, Sugg fades away and Wimsey's relations with the police become dominated by his amicable partnership with Parker, who eventually rises to the rank of Commander (and becomes Wimsey's brother in law).
