Mystery Teens Ride East

I'm making an RPG about mystery-solving teens. Just ran a playtest session using the Orient Express mystery-o-matic. They ended up taking a ride with

Rupert Coldsing. Twelve year old chain smoker, travelling alone, turned out to be an expert on defusing bombs. By finding this bible verse, deciphering a code, and hacking into the frequency of his secret radio, the gang discovering that he was a secret agent of communist-nazi spy agency Leviathan, working together with

Lokman Yilmaz, Turkish hypnotist and master of illusion. Both he and Rupert were working together to hunt down whoever stole the Key to Shangri-la from Leviathan. Lokman and Rupert were threatening

Count Frumpenshire Hamffleswain, famed Shakespearean actor, surrounded by silent servants with sewn-up waistcoats. The count had some bad debts, and was on his way to pick up his inheritance in Istanbul when Leviathan tracked him down. He was fine at first, but started to sweat after the murder of his personal friend,

Francis Depardue, suicidal French artist. From the occult symbolism of his paintings, the teen team deduced that both he and the count worshipped the same ancient, forgotten volcano god. Deeply depressed at the death of his religion, Depardue said this would be his last journey - so why was he found stabbed with his own ceremonial dagger? The culprit was taller than him - which means it was either Lokman, the Count, or

Beatrice von Trumpleshlize, obsessive german monkey collector. After stealing the Key of Shangri-la, she was fleeing on the train with her husband:

Marco Catione, mild-mannered Italian priest and secret ice robot from another dimension. On a hunch, the teens burst into his cabin and interrogated him. Believing they worked for Leviathan, he revealed his true form and froze one of the teens solid. With some home-made explosives the gang blew up the carriage and escaped off the train.

Now the teens are in the middle of the Austrian wilderness with Marco's severed robot head and the stolen Key to Shangri-la. If they can get to the Himalayas alive with that key, they could unlock the greatest mystery of our time - but all these crazed treasure-hunters and the forces of Leviathan are ahead of them.
