The look on the driver’s face was everything Sokolov had hoped for. But he had already cut his engine and drifted in close. He reached down to shift his propeller into reverse gear, but Olivia hooked her arm into his and prevented it. The boat drifted closer. Sokolov vaulted over the causeway’s railing and slammed down onto its prow, then dove over its windscreen and came up onto his feet in time to intervene in a physical squabble between Olivia and the driver. He got the latter in a very simple armlock, just to focus his attention, and then let him see the submachine gun.
