The Patrician stopped and prodded at one of the drawings.
‘There’s a piece of yellow paper stuck to this one,’ he said, suspiciously. He pulled at it. It came away from the drawing with a faint sucking noise, and then stuck to his fingers. On the note, in Leonard’s crabby backward script, were the words: ‘krow ot smees sihT: omeM’.
‘Oh, I’m rather pleased with that,’ said Leonard. ‘I call it my “Handy-note-scribbling-piece-of-paper-with-glue-that-comes-unstuck-when-you-want”.’
The Patrician played with it for a while.
‘What’s the glue made of?’
‘Boiled slugs.’
The Patrician pulled the paper off one hand. It stuck to the other hand.
