The Lord Peter Wimsey Mysteries Volume Three: Murder Must Advertise, The Nine Tailors, Gaudy Night, and Busman's Honeymoon (The Lord Peter Wimsey Mysteries Boxset Book 3)

This collection contains four novels featuring Lord Peter Wimsey, a British aristocrat and detective. A Great War veteran with shell shock, Wimsey pursues criminal investigations alongside his hobbies of collecting rare books and sampling fine wines. In Murder Must Advertise, Victor Dean falls down an iron staircase at Pym's Publicity advertising agency and dies from a cracked skull. His replacement, a copywriter named Death Bredon, arrives shortly after. Bredon proves skilled at advertising margarine, alarm clocks, and nerve tonics, but he is actually Lord Peter Wimsey investigating Dean's death. The Nine Tailors follows Wimsey and his manservant Bunter during a countryside visit. The local rector invites them to ring bells for the New Year, but they instead encounter a murder, a mutilated corpse, and a decades-old jewel theft connected to ongoing deaths in the community. In Gaudy Night, mystery novelist Harriet Vane, an acquitted murder suspect, attends her Oxford college reunion. She receives poison-pen letters calling her a "dirty murderess," and the threats escalate. She seeks Wimsey's help to identify a killer among Oxford's dons.
