The solution suggested to him by a friendly publisher was to write crime fiction under a pseudonym -Edgar Box- and Vidal quickly (he claims eight days each) penned three crime novels, all set around the New York City are “Death in the Fifth Position” (1952), “Death before Bedtime” (1953), and “Death Likes it Hot” (1954), featuring Peter Cutler Sargeant II, a publicist turned private eye. Sargeant is a stand-in for the traditional private eye. He gets involved with murder, but he has no official role, other than being involved.
This is perhaps the least enjoyable of the three. The setting here is Senator Rhodes’ house in Washington D.C. The senator has hired Sargent in preparation for his aspiring presidential campaign. A bevy of other guests also arrive to spend the weekend with the senator, including his daughter Ellen who Sargent was briefly secretly once engaged to and meets on the train heading to D.C. for an impromptu rendezvous. Ellen, for fun, tells her parents that Sargent and her are currently engaged, though, leading to a bit of awkwardness as the Senator has just hired Sargent.
The Senator though has a bit part in this novel as he is quite quickly blown to smithereens by an explosive added to the fireplace in his den. The police detective Winters sizes up the situation and announces that all the houseguests are proper suspects and they are not to leave the house (without special permission) let alone the city.
What follows then is a sort of hotel in the Catskills mystery but here the isolated hotel is a mansion in the heart of the city. Various family secrets are spilled. There are beneficiaries to the will who did not even know his connected they were with the Senator. There are secret contracts sent surreptitiously. There are regular musical beds and finger pointing.
Sargent manages at the end to solve the puzzle which the local police had been unable to pierce. Indeed, he lays out his logic step by step to the guilty party.
