The Magic Mousetrap (audio story)

 was the one hundred and twentieth monthly Doctor Who audio story produced by Big Finish Productions. Originally, this story was meant to feature Agatha Christie during the time of her disappearance in December 1926. These elements were written-out due to The Unicorn and the Wasp providing an alternative take on the same historical events.

Publisher's summary
Switzerland, 1926: the Doctor finds himself halfway up an Alpine mountainside, on his way to an exclusive sanatorium for the rich and famous run by the Viennese alienist Ludovic 'Ludo' Comfort. In between bouts of electric shock therapy, Ludo's patients — including faded music hall turn Harry Randall, chess grandmaster Swapnil Khan and Lola Luna, darling of the Weimar cabaret scene — fill their time with endless rounds of Snap!, among other diversions.

But the Doctor soon suspects that someone's playing an altogether more sinister game. Someone with a score to settle…
