Here, in a small village, everyone knows Mr Papillon, for after all he's been delivering the mail on his bicycle for many years, always cheerful and smiling. He knows the villagers very well and even their little secrets...even better than anyone suspects.
Of course, he has never opened anyone's mail-that would be unthinkable!
Every postman knows that this is one rule that cannot ever be broken.
Not unlike the other villagers, Mr Papillon has also a well-kept secret of his own.
It is safely hidden under the jacket of his uniform...but for how long?
