For Operation Midnight Climax, the CIA rented safe houses—referred to by White as “pads”—in New York and San Francisco. The more infamous of the two, the San Francisco safe house, was decorated with, as Marks wrote, “items that gave the place the air of the brothel it was to become: Toulouse-Lautrec posters, a picture of a French cancan dancer, and photos of manacled women in black stockings.” Microphones were planted in the bedroom and an observation mirror was built into the wall. With Gottlieb’s blessing, White concocted the following plan: he would recruit sex workers to bring clients to the safe house, where they would give their clients LSD-laced drinks, and White would observe the effects of those drinks on clients. In return, he gave the women “chits,” each good for one favor. The next time a woman was arrested, she could give the officer White’s number to call and she’d be bailed out.
