FOR A MOMENT it was June 1941, and I was back with my reserve police battalion, the 316th, on the road to Smolensk, at a place called Goloby, in the Ukraine, holstering my pistol. I was the officer in charge of a firing squad that had just executed a security unit of NKVD. This particular unit had recently finished murdering three thousand Ukrainian prisoners in the cells of the NKVD Prison at Lutsk, when our panzer wagons caught up with them. We shot them all. All thirty of them. Over the years I had tried to justify this execution to myself, but without much success. And many were the times when I woke up thinking about those twenty-eight men and two women. The majority of whom just happened to be Jews. Two of them I’d shot myself, delivering the so-called coup de grâce. But there was no grace in it. You could tell yourself it was war. You could even tell yourself that the people of Lutsk had begged us to go after the unit that had murdered their relatives. You could tell yourself that a bullet in the head was a quick, merciful death compared to what these people had meted out to their prisoners—most of them burned to death when the NKVD deliberately set fire to the prison. But it still felt like murder.

AND WHEN I WASN’T LOOKING at the two bodies lying by the side of the road I was watching the police van parked a few meters away, and the several, frightened-looking occupants of its brightly lit interior. Their faces were bruised and bloodied and full of fear. It was like staring into a tank full of lobsters. You had the impression that at any moment one of them might be taken out and killed, like the two on the grass shoulder. Then the officer checked my identity card and asked me several questions in a nasal, cartoonish voice that might have made me smile had the situation seemed less lethal. A few minutes later, I was free to proceed with my journey back to Vedado.

I drove on for about half a kilometer and then stopped at a little pink stone café by the roadside, where I asked the owner if I might use the telephone, thinking to call Finca Vigía and warn Noreen—and, in particular, Alfredo López—about the roadblock. It wasn’t that I liked the lawyer so much. I never yet met a lawyer I didn’t want to slap. But I didn’t think he deserved a bullet in the back of the head—which, almost certainly, was what would happen to him if the militia found him in possession of those pamphlets and a pistol. Nobody deserved that kind of ignominious fate. Not even the NKVD.
