We witness what human beings are capable of doing to each other. Having experienced the worst, we must live for the best. We have to turn away from the horror.
We must fight our way out of the darkness, even if we do not live to see the light ourselves.
The story of how a soldier became a priest after fighting in WWII. I enjoyed how gentle it was although I can't imagine that I'll read the rest of the series: the Grantchester mysteries which apparently tell of how the priest goes on to solve crimes.
