“My dad was a fairy," said Zach. "And by that I don't mean he dressed well and enjoyed musical theatre.”

“When I was a kid I used to drink from the tap all the time. I'd run back into the flat all hot and sweaty from playing and didn't even bother putting it in a glass, just turned the tap on and stuck my mouth underneath it. If my mom caught me doing it she used to scold me, but my dad just said that I had to be careful. 'What if a fish jumped out?' he used to say. 'You'd swallow it before you knew it was there.' Dad was always saying stuff like that and it wasn't until I was seventeen that I realised it was because he was stoned all the time.”

“Despite my mum being from a small village in the middle of a forest, I'm not a country person. I don't like my bacon sandwich to be curiously snuffling at my fingers. But sometimes being police means holding your breath and fondling a pig.”

“What's the biggest thing you've zapped with a fireball?' I asked.'That would be a tiger,'said Nightingale.'Well don't tell Greenpeace,' I said. 'They're an endagered species.''Not that sort of tiger,' said Nightingale. 'A Panzer-kampfwagen sechs Ausf E.'I stared at him. 'You knocked out a Tiger tank with a fireball?''Actually I knocked out two,' said Nightingale. 'I have to admit that the first one took three shots, one to disable the tracks, one through the driver's eye slot and one down the commander's hatch - brewed up rather nicely.”

“My Dad says that being a Londoner has nothing to do with where you're born. He says that there are people who get off a jumbo jet at Heathrow, go through immigration waving any kind of passport, hop on the tube and by the time the train's pulled into Piccadilly Circus they've become a Londoner.”

“Conflict resolution,' said Nightingale. 'Is this what they teach at Hendon these days?''Yes, sir,' I said. 'But don't worry, they also teach us how to beat people with phone books and the ten best ways to plant evidence.”

“You put a spell on the dog," I said as we left the house."Just a small one," said Nightingale."So magic is real," I said. "Which makes you a...what?""A wizard.""Like Harry Potter?"Nightingale sighed. "No," he said. "Not like Harry Potter.""In what way?""I'm not a fictional character," said Nightingale.”
