Which is a good time to get back to the rambling buildings of Unseen University and in particular the apartments of Greyhald Spold, currently the oldest wizard on the Disc and determined to keep it that way.
He has just been extremely surprised and upset.
For the last few hours he has been very busy. He may be deaf and a little hard of thinking, but elderly wizards have very well-trained survival instincts, and they know that when a tall figure in a black robe and the latest in agricultural handtools starts looking thoughtfully at you it is time to act fast. The servants have been dismissed. The doorways have been sealed with a paste made from powdered mayflies, and protective octograms have been drawn on the windows. Rare and rather smelly oils have been poured in complex patterns on the floor, in designs which hurt the eyes and suggest the designer was drunk or from some other dimension or, possibly, both; in the very centre of the room is the eightfold octogram of Witholding, surrounded by red and green candles. And in the centre of that is a box made from wood of the curly-fern pine, which grows to a great age, and it is lined with red silk and yet more protective amulets. Because Greyhald Spold knows that Death is looking for him, and has spent many years designing an impregnable hiding place.
He has just set the complicated clockwork of the lock and shut the lid, lying back in the knowledge that here at last is the perfect defence against the most ultimate of all his enemies, although as yet he has not considered the important part that airholes must play in an enterprise of this kind.
And right beside him, very close to his ear, a voice has just said: DARK IN HERE, ISN'T IT?
