I liked it better than the other Dorothy Sayers.
Lord Peter goes undercover at an advertising agency to investigate a suspicious death. He finds he has a knack for copywriting, as well as solving mysteries. My favourite scenes are the ones devoted to the ad agency, its office workers and their work. It’s like Mad Men but more innocent. The murder investigation becomes a hunt for drug dealers. Fun parts: Lord Peter has to bluff his way out when his undercover and real lives clash. Dumb parts: Lord Peter is too perfect: a friendly, flawless Sherlock Holmes. And there’s no Bunter.
