When he did look back at last he did not see him, and he felt immediate elation.

It would not be long now until dark, and then he would make his escape across the river.
Time was slow, but it could not keep darkness back forever, and, as soon as it had come fully, he turned toward the north.

Southern troops would not be looked for there, and egress would be easier in that direction.
He passed on without interruption and soon was in the suburbs, which were then so shabby.

Then he looked back, and cold fear plucked at the roots of his hair.

A man was following him, and he could tell even in the dim light that it was Shepard.
A shudder shook him now.
