Momo

The sinister men in grey were experts on time just as leeches are experts on blood. They visit innocent, undeveloped characters in poor novels, like Mr Figaro, the barber, and frighten the life out of them. Time saved is time doubled. Don't worry about it, even if you get to the end of the story, you'll wonder why you bothered. Is Momo a witch? Is Guido a guide, or an agent for the KGB/CIA/BBC or any other mnemonic that takes your fancy? Timesharing I've seen advertised, but Timesaving is about to boom big if the men in grey have their way. I'm sure it could all be heavily psychological, but I don't think your average eleven year old is going to wait around long enough to decipher it.
