‘You know, this looks exactly like the sort of place where a mystery might happen!’

There are many places the twins would rather be than stuck on a spiritualist retreat. But things become interesting when famous escape-artist Harry Houdini shows up on the island to expose the money-grabbing spiritualists. However, when he disappears without a trace, it soon becomes clear that it’s not of his own doing – he’s been kidnapped! It’s up to Christie and Agatha to help him in his most daring escape yet.

About the Christie and Agatha's Detective Agency series:

But when a scientific discovery goes missing, they find that together they make a winning combination and Christie and Agatha’s Detective Agency is born. Join the twin detectives as they solve thrilling mysteries all over the world!
