It is the mysterious Ministry of Letters, the place where all the words in the world are made. Believe it or not, every single word you'll ever read - even these - started life inside this not-so-ordinary post box.

Charlie Foxtrot has just started school and finds learning the alphabet strange and confusing. Luckily, Charlie's struggles are spotted by two agents from the top secret Ministry of Letters, who summon the Special Alphabet Service (S.A.S.) to the rescue. Boarding trains, dodging hungry cats, and personally escorted by a dashing Duchess, the 26 letters of the Special Alphabet Service embark on a thrilling adventure to find Charlie, teach him the alphabet and open his mind to a love of letters and stories.
