But things go wrong. Johnson is pursued by his nemesis, the vengeful Russian oligarch Yuri Severinov. And subsequent events turn out to be vastly more complex and terrifying than he expected. Why are ex-KGB and Stasi intelligence chiefs so anxious to prevent Johnson from getting to the heart of what really happened? And what are the Kremlin connections that suck him into a life-or-death chase in St. Petersburg? Johnson and his ex-MI6 colleague Jayne Robinson find themselves battling against the odds to dig out truths that have been concealed for almost thirty years.

The key to solving the conundrum around the Berlin bombing comes from an unlikely direction, and the identity of the Russian mole who is wreaking havoc in the West turns out to be equally surprising. The story works its way to a climax in London and Leipzig as Johnson battles against overwhelming odds to outwit the forces arrayed against him. is a thriller with many unexpected twists that will keep the reader guessing right to the end.
