The Secret War Against Sweden [EPUB ebook] 
US and British Submarine Deception in the 1980s

Following the stranding of a Soviet Whiskey-class submarine in 1981 on the Swedish archipelago, a series of massive submarine intrusions took place within Swedish waters.However, the evidence for these appears to have been manipulated or simply invented. Classified documents and interviews point to covert Western, rather than Soviet activity.
