'It was not in fact locked, as you see,' he said, 'and you are forbidden to come within fifteen yards of me. I have an injunction.'
'And you are not allowed to be within twenty yards of me, so you broke it first,' said Pucci, pulling up a chair. She straddled it heavily and rested her arms on the back. The wood creaked.
'I wasn't the one who moved, I think?'
'Well, cosmically it's all the same,' said Pucci. 'You know, that's a dangerous obsession you have there.'
Now Cosmo took off the cap. 'I'm simply trying to get inside the man,' he said.
'A very dangerous obsession.'
'You know what I mean. I want to know how his mind works.'
'And this?' Pucci said, waving a hand at the large picture that hung on the wall opposite the desk.
'William Pouter's Man with dog. It's a painting of Vetinari. Notice how the eyes follow you around the room.'
'The dog's nose follows me around the room! Vetinari has a dog?'
'Had. Wuffles. Died some time ago. There's a little grave in the palace grounds. He goes there alone once a week and puts a dog biscuit on it.'
'Vetinari does that?'
'Yes.'
'Vetinari the cool, heartless, calculating tyrant?' said Pucci.
'Indeed!'
'You're lying to your sweet dear sister, yes?'
'You can choose to believe that if you wish.' Cosmo exulted, deep inside. He loved to see that irate-chicken expression of furious curiosity on his sister's face.
'Information like that is worth money,' she said.
'Indeed. And I'm only telling you because it's useless unless you know where he goes, at what time, and on which day. It just may be, dear sweet Pucci, that what you call my obsession is in fact of great practical use. I watch, study and learn. And I believe that Moist von Lipwig and Vetinari must share some dangerous secret which could even - '
'But you just weighed in and offered Lipwig a bribe!' You could say this about Pucci: she was easy to confide in because she never bothered to listen. She used the time to think about what to say next.
'A ridiculously small one. And a threat, too. And so now he thinks he knows all about me,' said Cosmo, not even trying not to look smug. 'And I know nothing about him, which is even more interesting. How did he turn up out of nowhere and immediately get one of the highest jobs in - '
'What the hell is that?' demanded Pucci, whose massive inquisitiveness was hampered by the attention span of a kitten. She was pointing at the little diorama in front of the window.
'That? Oh - '
'Looks like an ornamental window-box. Is it Toytown? What's that all about? Tell me right now!'
Cosmo sighed. He didn't actually dislike his sister - well, more than the natural basic feeling of irksomeness all Lavishes felt for one another - but it was hard to like that loud, nasal, perpetually irritated voice, which treated anything Pucci didn't immediately understand, which was practically everything, as a personal affront.
'It is an attempt to achieve, by means of scale models, a view similar to that seen from the Oblong Office by Lord Vetinari,' he explained. 'It helps me think.'
'That's crazy. What kind of dog biscuit?' said Pucci.
Information also travelled through Pucci's apprehension at different speeds. It must be all that hair, thought Cosmo.
'Tracklement's Yums,' he said. 'The bone-shaped ones that come in five different colours. But he never leaves a yellow one because Wuffles didn't like them.'
'You know they say Vetinari is a vampire?' said Pucci, going off at a tangent to a tangent.
