The Police woman declared undying love for Peter Howitts character and said she wanted to "have relations" with him.
They went off in his car, then his real wife (who he and everybody else thought was dead) turned up at the police station.
They got the news the undercover woman had done the off with the bloke so Daniel Craig's character got his real wife to take them to where he buried her.
In the mean time the other two are getting busy in the car after a full confession, only for him to to open her top and reveal a mirophone (why you would take a potential murderer to a secluded spot to get a full confession using sex as the method and then attach the microphone to your bra I'll never know).... anyway he goes beserke and attaches a hose pipe to the car exhaust and tries to gas them both.
In the mean time having chased round loads of woods Daniel Craig turns up and saves the day.
