The Case of the Golden Bullet

A series of detective cases features Joseph Muller, a modest secret-service investigator shaped by a past wrongful imprisonment and constrained by bureaucratic rank. The principal narrative opens with a college professor found dead in a locked room, his valet alarmed by the silence and the key turned on the inside, prompting Commissioner Horn to call Muller. The account follows Muller’s meticulous, almost obsessive inquiry as physical clues and hidden relationships are unraveled, and depicts his frequent conflicts with official protocol and his propensity to temper strict justice with personal compassion.
