As recounted in the short story "The Adventurous Exploit of the Cave of Ali Baba", in December 1927 Wimsey fakes his own death, supposedly while hunting big game in Tanganyika, to penetrate and break up a particularly dangerous and well-organised criminal gang. Only Wimsey's mother and sister, the loyal Bunter and Inspector Parker know he is still alive. Emerging victorious after more than a year masquerading as "the disgruntled sacked servant Rogers", Wimsey remarks that "We shall have an awful time with the lawyers, proving that I am me." In fact, he returns smoothly to his old life, and the interlude is never referred to in later books.
