Nero Wolfe - INTJ detective in many books by Rex Stout
Nero is a regimented and reclusive genius who solves crime in New York during the mid-twentieth century with the help of his (probably) ISTP secretary Archie Goodwin. Unlike many detective stories, the detective stays in the office and the secretary does all the legwork.
“There are two novels that can change a bookish fourteen-year old’s life: The Lord of the Rings and Atlas Shrugged. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs.” ~ John Rogers
