“Let’s go,” he told his childhood friend, Viktor Borisenko, after picking him up in his car. It was clear to Borisenko that something had happened, but Vladimir would not so much as hint at what it was. They went to a Georgian restaurant near the Kazan Cathedral, the colonnaded landmark on Nevsky Prospekt, eating chicken in walnut-sauce and, to Borisenko's surprise, for his friend had never before allowed the indulgence, drinking shots of sweet liqueur. Only much later did he learn that they had been celebrating his friend’s acceptance into the KGB.
