Yves Lavigne is a Canadian journalist who has spent many years researching outlaw motorcycle gangs. He is considered to be the North American expert on the Hell's Angels motorcycle club, and he has written several books about them. Lavigne's first book, Hell's Angels: Taking Care of Business, was published in 1987. In his next book, Hell's Angels: Three Can Keep a Secret If Two Are Dead, Lavigne chronicled the metamorphosis of the Hell's Angels, from its beginning, now nearly forgotten, as a stateside club for World War II fighter pilots to its contemporary involvement in organized crime. These books caused a friend of his to suggest that Lavigne write the story of Anthony Tait, an… informant who infiltrated the highest ranks of Hell's Angels while helping the FBI to conduct an undercover sting operation. Lavigne agreed to meet Tait and, in 1992, began interviewing him about his involvement in Hell's Angels and his role in the FBI operation. Lavigne conducted some of the interviews while traveling through California with Tait, who, now a target for retaliation, carried a small arsenal with him and kept a gun by his bed at night. Tait's story is told in Hell's Angels: Into the Abyss.
