Rayner J.: Doctor Who: Magic of the Angels

The Doctor, Amy and Rory round off a sight-seeing tour round London with a trip to the theatre. That's when things start to go wrong. The Doctor wonders why so many young girls are going missing from the area. When he sees Sammy Star's amazing magic act, he thinks he knows the answer. Sammy's glamorous assistant disappears at the climax of the act - but this is no stage trick.
