He came to a point where he could definitely hear the jihadists making their way through the trees, and then it became a matter of calibration: he didn’t have as far to travel now, but he had to do it more carefully. They did not appear to think that he was nearby. Perhaps they believed that, in shooting the effigy atop the rock, they had killed Sokolov. Perhaps they had become confused as to geography. In any case, they did not know that he had come around from another direction to engage them, and as long as they remained in that state of ignorance he had a huge advantage that could be lost in an instant if he behaved indiscreetly. And so the last part of Sokolov’s journey was a reenactment of the very worst moments of his special forces training: he spent the whole time crawling on his belly, at first over sharp rocks and then over sopping ice-cold mud overgrown with thorny and poky vegetation.
