If Chechen suicide bombers blow up the dam of a power plant under construction, the rushing water will flood a vast territory of forest areas and take thousands of human lives. At the same time, the oil holding “Staroil” will receive a huge insurance payout. This is the plan of a former intelligence officer codenamed Delon. The plan cannot be faulted—if not for one flaw. Preparation for the terrorist attack became known to a deputy colonel of the FSB, Viktor Loginov. And that means it’s time for him to start serious work. First, he must stop the train carrying explosives, and then figure out the treacherous terrorist. Especially since they are old acquaintances.
