‘I grew up in Rookery Yard in the Shades. They’re in Ankh-Morpork,’ said Henry. 'It was a terrible rough place. There were only three ways out. You could sing your way out or you could fight your way out.’
'What was the third way?’ said Nanny.
'Oh, you could go down that little alleyway into Shamlegger Street and then cut down into Treacle Mine Road,’ said Henry. 'But no one ever amounted to anything who went that way.’
