Secret Service

You are secret service agents on a special assignment in London to prevent a terrorist attack. During the operation, you discover that one of the agents is leaking information to the terrorists. The double agent immediately disappears without a trace. You need to relay the information to headquarters, but using internal channels is no longer safe. Therefore, you went to the nearest telephone booth to make a call, but fell into a trap. Now you have to get out on your own and save London from an explosion.
