To: Sergeant Carrie McCall Subject: Regarding Reilly Your assignment flouts two cardinal rules of the cop code: Never investigate your partner and never fall for your partner. You will do the first, plumbing Sergeant Lincoln Reilly's home and psyche for proof, even as you pretend to be lovers on a covert sting. Because despite an exemplary record, circumstantial evidence suggests that Reilly kills acquitted criminals as coldly as the worst offender. Beware of the second.Reilly's instincts have never failed. And with you, he appears to be operating on the most basic instincts between man and woman. Trust only your training...or stand to lose more than your cover.
