Amnesia

This dandy British miniseries stars John Hannah ("Four Weddings and a Funeral," "Sliding Doors" and "The Mummy"). He is a detective working on a missing person case. His own wife has gone missing and it is causing him no end of emotional grief - he's drinking too much, is hallucinating and is generally deteriorating. His sidekick has to awaken him each day to get him to work...late but at least to work...

His fixation leads him to the conclusion that his "missing person" case is inextricably tied to a well-known case of amnesia that is being studied at a nearby medical facility. As he becomes more and more convinced of the link, he also alienates his coworkers -- more and more. He also alienates the well-known amnesiac and his new wife, because that fellow has created a new life for himself and isn't sure he WANTS to remember his past.

John Hannah is a terrific actor and he is super in this role.

BIG caveat! No captions! I turned the volume waaaay up and was able to get most of the dialog, but never heard the resolution to the blood in the carpet padding.... If you watch this, maybe you can tell me...
