Tgo it! from a loyal codebreaker

Dear Word Spy,

I know your code!
It is: "Codes like this can drive you crazy!"

Each word has a different rule, but it's pretty hard to say what rule! :-(

Your loyal codebreaker,
Sam

Dear Loyal Codebreaker Sam,

Well done again! that was quick. You are absolutely right. You have worked it out by instinct - but the actual rule is that you take the third letter of the word and put it at the front of the word. (Of course this does not work so well for two letter words...)

I will have to come up with a more fiendish code to test you now. Off I go to think about it!

yours in admiration,

The Word Spy
