to no one without the face image." The guard had drawn back into his cubby; there was only his extended hand and the muzzle of his weapon left visible. I took a step forward. "I don't want to talk by phone. Won't you open the gate? It's cold out here. We have important business. We'll wait with you." Abruptly the gate lattice slid aside. Beyond the cubby doorway was the open darkness within the wall. A scuffed path leading inward from the gate showed for a few feet. I walked over the threshold, with Alan crowding me. The Essen in my coat pocket was leveled. But from the cubby doorway, I saw that the guard was gone! Then I saw him crouching behind a metal shield. His voice rang out.
