I know there's Brooklyn and all the boroughs, but Manhattan specifically is so condensed that the energy is very vibrant. Everywhere you look there is something happening.

I don't think I believe in ghosts, per se. But, my nearest experience was when I went on a weekend away and was in a bar in England, years ago, with an ex-girlfriend. I heard this scratching. I was about to go to bed and I was thinking, 'It's an old ghost.' I could hear this noise, but I couldn't work out where it was coming from.

New York cops are very specific in terms of the way they talk and the way they handle themselves. All these cliches that, as an Englishman, I thought were from a bygone era or were a bit of poetic license with cop shows - the more you hang out with them, the more you realize how real that jargon is.

To me, the difference between New York and London is that things are boring and staid in London.

I know I often get a job because of how I look. I hope that I keep the job because of how I act.

New York police force seems like unlike any other in America and even the world. There's a very specific culture dynamic, a specific chemistry. There's almost a specific set of rules because of the city and the size of it.

I've got two brothers and two sisters, so there's five of us and we're all very close, which is cool.
