The 69th Parallel Incident — H. Paul Doucette

Late one night, while tending to his trap-line, a native Inuit stumbles across a clandestine rendezvous not far from one of the DEW line radar sites and is subsequently shot and killed. This incident brings RCMP intelligence officer, Inspector Jesse Thompson to the north. He gradually uncovers a Soviet network involving an agent and a paid mole in the Shingle Point site.
