Dorothy L. Sayers’ 1923 debut mystery novel “Whose Body?” is a classic cozy mystery featuring the debonair aristocrat-sleuth Lord Peter Wimsey. After a corpse wearing pince-nez glasses is found in a bathtub, Lord Peter undertakes to investigate the deed privately. But determining whether the corpse belongs to a well-known banker or a group of mischief-making medical students is just the beginning of this tangled mystery plot. This atmospheric novel put Dorothy L. Sayers in the ranks with Agatha Christie as a mystery writer nonpareil.
