Law & Order: Criminal Intent (2001) : 5x3

Prison warden William Hendry is found brutalised after he goes to drop off a large ransom payment for his wife, kidnapped years earlier by an escaped convict. Eames and Goren track down Jenny Hendry, living happily under a new name, and begin to realise that Hendry isn't the squeaky clean martyr that he's been portrayed as for years, especially once they discover that Jenny's supposed 'kidnapper' was originally hired by the warden to kill his wife.
