THREE DAYS NORTH of the Danube, the road focused to a rut in a crowd of scrawny trees that were striving to rise clear from a haze of grasping weeds. The weeds seethed with bugs and stirred with small unseen beasts. Paving-blocks skewed out of pounded ground, forming a sort of shoal that unsettled Turk, who straightened, blinked suspiciously, and slowed.

When it was clean, he stood in a buttress of sunlight, thigh-deep in brown water, nervously wiping it and swinging it in the air.
