His 1983 account of the Jeffrey MacDonald murder case, "Fatal Vision", became a sensation and has never been out of print. MacDonald sued McGinniss in 1984, alleging that McGinniss pretended to believe MacDonald innocent after he had already come to the conclusion that MacDonald was guilty, in order to continue MacDonald's cooperation with him. After a six-week civil trial in 1987 that resulted in a hung jury, his publisher's insurance company chose to settle out of court with MacDonald for a reported $325,000.
