"The Spy" and "Queen of the Highway" celebrate Morrison's intense but troubled relationship with longtime girlfriend Pamela Courson. Originally "The Spy" was called "Spy in the House of Love", as shown on the Master Reel Control File, a line borrowed from "A Spy in the House of Love", a novel by Anaïs Nin published in 1954. Both songs are tinged with ambivalence; on "The Spy" Morrison cautions, "I know your deepest, secret fears", while on "Queen of the Highway" he sardonically concludes, "I hope it can continue a little while longer". According to the 1980 Doors biography "No One Here Gets Out Alive", it was during the "Morrison Hotel" sessions that Morrison and Courson had a violent argument after she drank his bottle of liquor so he could not drink it, with engineer Bruce Botnick recalling: "So here were the two of them, completely out of their minds and crying. He started shaking her violently. I think he was putting me on. She was crying out of control, telling him he shouldn't drink anymore and that's why she drank it. And I'm cleaning up and I said, "Hey man, it's pretty late." He looked up, stopped shaking her, said, "Yeah, right", hugged her and they walked out arm in arm... he'd always give you a funny look afterward, to see your reaction."
