I have always been fascinated by the letter Q. It is elusive. It is tantalizing. It is frustrating and recalcitrant. But with kindly and gentle persuasion it can be manipulated -- sometimes. I would guess that 99 per cent of the time it is followed by the letter U with another vowel or two. It is the other 1 per cent that makes it so interesting.
