Having finished his preparations, Abdul-Wahaab made one last orbit around the big SUV, inspecting his work, then reached into the open driver’s-side door. Zula heard a distant thunk as he released the parking brake. The Suburban began to roll forward down the ramp. He walked, then ran alongside, keeping his right hand on the steering wheel, then peeled away from it just before it nosed into the water. It lost most of its velocity in the first few yards, plashing up a concentric wave that spread out into the lake, but it never stopped moving. Air burbled up out of the engine compartment. It slid forward into the lake, instantly filling with water, and disappeared, leaving a trail of bubbles that slowly moved away from shore as the vehicle found its way down to the lake bottom. The terrain all around was rocky and steep, and Zula had no doubt that the bottom dropped away precipitously beyond the end of the paved ferry-ramp. The lake must be a hundred meters deep, and the Suburban would come to rest at the very bottom of it.
