But thing that drove Alvarez crackers was that phone numbers for Adam were reported and every time they turned out wrong numbers. (Not nulls; we had run out and Mike was using any number not in use and switching numbers anytime new subscribers were assigned ones we had been using.) Alvarez tried to trace "Selene Associates" using a one-wrong-digit assumption—this we learned because Mike was keeping an ear on Alvarez’s office phone and heard order. Mike used knowledge to play a Mikish prank: Subordinate who made one-changed-digit calls invariably reached Warden’s private residence. So Alvarez was called in and chewed by Warden.
