Season 11: Episode 21 - Cello and Goodbye

Cello and Goodbye: Picking up where we left off in episode #1120. Our CSIs head to L.A after Nate Haskell takes Langston's ex-wife Gloria hostage. They are called to a crime scene where they find the body of Gloria's husband, Phil who has been stabbed multiple times but there is no sign of Gloria. Langston's world is turned upside down as he tries to follow the steps of a madman. Langston pretends to head back to Vegas because he simply is too close to this case, but when he goes rogue, Nick tracks him down and helps Langston connect the dots. The team finds out that Tina has been killed by Haskell -- as he just uses the brides and discards them one by one. Langston is the only one who realizes that Haskell has headed back to Vegas and he follows him back to the old farmhouse. Langston discover Gloria is the farmhouse barely alive as Haskell’s true identity is revealed. The episode ends in a stand-off between Langston and Haskell.
