Mystery Novel about Washington Intelligence . This 1974 novel used sources like "The Politics of Heroin in Southeast Asia" by Alfred W. McCoy, and the others listed in the 'Preface'. It takes place in Washington DC. Ronald Malcolm works for the "American Literary Historical Society", and reads detective and mystery novels to summarize its plots for his employer. One day their new accountant tells Malcolm there is a discrepancy in the records; of seven crates shipped from Seattle only five crates arrived in Washington. This had not been noticed previously. The accountant reports this loss in a memo. Malcolm reports to work on Thursday. It is his turn to go out for sandwiches for lunch, and he uses a basement exit for a short-cut. He also runs an errand. He returns to find the front door locked; he has to use his key. Then he finds that all of his co-workers have been killed by professional assassins. Malcolm leaves the building and calls the "panic number" from a public phone to report the maximum damage; he is told to disappear and call back later. When Malcolm calls back, he is told to make contact in an alley of a Georgetown theater. But his rescue team takes a shot at Malcolm, who fires back, escapes, and goes to ground. Will Malcolm be rescued by he CIA or found by the killers? And who is the double agent? After you read this novel you can better understand the film, which is a simplified and condensed version (called "Three Days ...). The story was changed from drug smuggling (to censor drug references?), and relocated to NY city. This story seems implausible to me, since eliminating the one link in Seattle would avoid the furious investigation that would follow a massacre of seven in Washington DC.
Output:
POS
