When the last honest citizen of Poisonville was murdered, the Continental Op stayed on to punish the guilty--even if that meant taking on an entire town.
"Red Harvest" is more than a superb crime novel: it is a classic exploration of corruption and violence in the American grain.
The Op was in Personville, derogatory nickname aside, as the result of a letter to the Continental Detective Agency in San Francisco from Donald Willsson, publisher of the local paper, asking for an agent to visit. No other information. As soon as the OP arrives, the body count begins. It starts with his client!
