SOKOLOV HAD A key card that would enable him to summon an elevator, but he reckoned that the jihadists might be down in the lobby, in view of the indicator panel. They might notice one of the lifts going into motion and stopping at 43. If so, they could simply kill him when the door opened. So he took the stairs instead, just as Zula had done the other day. He took them fast, bounding over banisters and caroming off walls. But he was still moving a hell of a lot slower than those guys in the elevator.
