A murder, a mystery and Agatha Christie
Status
Summary
Rose Tyler wants to go back to the 1930's to take a trip on a boat down the river Nile. The Doctor agrees and they manage to sneak on board to find none other than Agatha Christie. Of course that means a murder so Rose and The Doctor offer to help but he has left the Tardis on dry land and there is nowhere to hide when the killer strikes again, narrowly missing Rose.
