Key passages
“I slew the man in Central Park. Now, let me describe myself to you. I am tall, with a black beard, and I hate publicity. I have no money to speak of; I do not like oatmeal, and it is the one ambition of my life to die rich.”
Knight describes himself as a tall, bearded man who shuns fame, is poor, dislikes oatmeal, and wants to die wealthy.
Knight uses this self-description to deduce the detective's opposite approach.
“I assumed that the detective would go exactly opposite to the clues he had. I have given you a description of myself. Therefore, he must necessarily set to work and trail a short man with a white beard who likes to be in the papers, who is very wealthy, is fond of oatmeal, wants to die poor, and is of an extremely generous and philanthropic disposition.”
Knight reasoned the detective would seek the opposite of his own traits, leading him to a short, white-bearded, wealthy, charitable man who loves publicity and oatmeal.
This explains how Knight located Jolnes staking out Andrew Carnegie's home.
