It had been very kind of him to take us in during a raging snowstorm on Christmas Eve, but I wish Joel would shut up about it. We’d been travelling along the edges of Białowieża Forest, trying desperately to get home to see family, when the car had broken down.

There was no mobile signal, of course, so we’d sat in the car, after the inevitable argument, shivering. Then, like the light of the Angel Gabriel, twin beams of a 4×4 had sliced through the blizzard, and Joel had been out in the road, waving his arms, trying to get a lift. Fortunately, the driver had stopped.
