To Catch a Mongoose - S2.E1

Amanda is sent to London when an old high-school friend, Conrad "Connie" Barnhill, is suspected of being a murderer labeled as the "Mongoose." This homicidal killer leaves a calling card at the scene of his crimes with the Mongoose written on it. Amanda tries throughout the entire episode to convince Lee that Mr. Barnhill is not the killer. Near the very end of the show, Amanda is kidnapped by the real Mongoose, forcing Lee on a chase through a foreign country.
