Solve the puzzle. Stop the baddies. Simple, right?
Step into the shoes of Arlo Banks, and return to a world of secrets, spies and diabolical plans.
It’s Christmas, and Arlo is hoping to finally start his top-secret training to become a proper spy.
But old enemies have other plans. When it turns out there’s a scheme to rob the Bank of England, Arlo must use all his puzzle-solving cunning to unravel the mystery.
As the temperature drops, and the snow falls, Arlo must delve into the vaults of the world’s most guarded building. What he find there isn’t gold and jewels, but something far more deadly.
It’s a discovery that will take him across the world, and put its future in his hands.
You choose what path you take, what puzzles you solve, and what answers you choose in this interactive high-stakes mystery.
