You are a secret agent in the service of the KGB, and after a setback when the higher-ups thought your cover had been blown, you have embarked on a highly dangerous mission to infiltrate MI6. Under the pseudonym of Flynn Smith, you are working undercover in London when you receive the following mysterious email.

You are confused: with all your expenses paid by the intelligence service, you never fly with a budget airline company like Ryanair. Perhaps they've got you mixed up with another Mr Smith - but how come your email address is on their records? Also there aren't even any ticket details in the email, only a nonsensical string of letters. The message must have been garbled.
But remembering your previous experience of an apparently spam email, you examine it more closely, wondering if there's a message hidden within it. After several minutes at your computer, you find the hidden message and your eyes widen. You reach for the drawer in which your handgun is stowed; you're in danger!
Looking even more closely, you realise that there's a second message hidden within the more obvious one. Your KGB agent handler is telling you where you must go - and probably also that you're in danger. It seems as though everything's under control, but you must move fast.
What is the hidden message?
