In the book, The Catcher in the Rye, who is Luce to Holden ?

Carl Luce, Holden's former schoolmate, ostensibly his Student Adviser, was about three years older and "one of these very intellectual guys—he had the highest I.Q. of any boy at Whooton."

Holden called him, hoping to have dinner and "a slightly intellectual conversation," but Luce could only meet him for a drink at the Wicker Bar at ten that evening.

He arrived saying he could only stay a few minutes, ordered a' martini, kept trying to get Holden to lower his voice and change the subject. Before leaving, he suggested that Holden call his father, a psychoanalyst, for an appointment.
