> It’s 1975. Your name is Thomas and you are a double agent for MI5. You are working in the field in the USSR, but you suspect letters you write and send back to the UK are being intercepted and read by the KGB. Write a letter to your wife Anita explaining your recent trip to a nearby restaurant but, using the first word of every paragraph of your letter, secretly reveal your suspicion that you’re being observed and request that MI5 charter a flight for you to return to the UK.

> Dear Anita,

> Recently, I traveled to a nearby restaurant for a much-needed break from my work in the USSR. However, upon returning, I began to feel as though I was being watched. Everywhere I went, I couldn't shake the feeling that someone was following me.

> It's possible that the KGB is intercepting my letters and reading them, so I must be careful with what I say. But I fear for my safety and want to return to the UK as soon as possible.

> I hope this letter reaches you safely and that you can communicate with MI5 on my behalf. Please request that they charter a flight for me to come home as soon as possible.

> I miss you and our children dearly and can't wait to be reunited with you all. Until then, please take care and stay safe.

> Yours always, Thomas
