Two police detectives - one, Somerset, about to retire and the other, Mills, just transferred into the precinct - investigate the murder of an obese man. On his wall was written the word "Gluttony". Then they are alerted to the murder of a lawyer. On his floor was written the word "Greed". Somerset suspects that the murders were the work of the same man, a man murdering people who have committed the seven deadly sins.—grantss
