" I mean like with the love of your life. Everybody’s got one person out there. One bullet. And if you’re lucky in life, you get to meet that person. And once you do, once you’re shot through the heart, then there’s nobody else. No matter what happens—death, divorce, infidelity, whatever—nobody else can ever come close. That’s the single-bullet theory. "

― Michael Connelly , The Scarecrow (Jack McEvoy, #2; Harry Bosch Universe, #19)
