Arlo Banks has always wanted to be a detective. And when he solves a fiendish puzzle in The Times, set by an elderly Oxford professor, he might just get his chance.

The reward for solving the puzzle was a trip of a lifetime - a journey on the famous Orient Express. It was a journey that took him from the pyramids of Egypt to the top-secrets spies of London.

Now Arlo is back. And faces more puzzles, and more mysteries. This time, the murders really are just the start . . .

Your choices could take you to the killer - or lead to a more unfortunate fate.
