“None of these men would admit that what they saw and what they did were beyond the boundaries of human behavior. You would not believe, Jack thought, that the fellow with his cap pushed back, joking with his friend at the window of the butcher’s shop, had seen his other mate dying in a shell-hole, gas frothing in his lungs. No one told; and Jack too joined the unspoken conspiracy that all was well, that no natural order had been violated.”
