Three drops of blood and a cloud of cocaine

the long version

"When old Jimmy Henderson is found murdered in his Ford pick-up truck in a suburb of Boston, Sheriff Paul McCarthy takes charge of the investigation. Soon, Franck, a young private detective visiting from New York, also takes an interest in the case. Breaking the conventions of the genre, the novel holds a satirical mirror to our society by entering the minds of two men right on the edge of sanity. Sheriff McCarthy, a church-going man, desperately trying to keep a boundary between the sordidness of his investigations and his private life. And Franck, a violent, decadent dandy, always rushing to the bathroom for another line of coke, revealing the darker workings of the case with a blood curdling laugh. When the two men finally meet the entire existence of the sheriff as a righteous family man--and probably as a police officer--will be turned on its head."--Amazon.com.
