Jessica is in Amsterdam for a writers conference. Soon after arriving, she meets up with an old friend, a fellow writer who is about to do a presentation with her. However, when the time comes, he's not there...and Jessica knows the guy wouldn't just walk away from the conference or her. Someone is trying to hide this, however, as soon she gets word that he's back in England...which makes absolutely no sense. There are quite a few twists and turns and eventually, naturally, Jessica sorts it all out and saves her friend from doom.
This is a mildly entertaining episode. I'm surprised it was the second episode of season 11 instead of the first, as in many previous seasons the first episode was set in some foreign land (episode one was set at an American zoo). My only complaint is that when a man shows up saying he works for British Intelligence, Jessica never contacts her old British Intelligence friend, Michael Hagarty for help or to confirm whether or not this other man is an actual agent.
