He carries a big, battery-powered torch.
In The Enemy
Nick is first seen in the tunnels as he carries Small Sam back into his train, into Bank. Across the platform they were in, there were small candles in glass jars to give it light.
He lives in the train with a woman who is round and jolly-looking, with a big woolly jumper and a long, wide skirt. She had a bush of greying reddish hair and a kindly face. She is called Rachel.
They both gain his trust by giving him food and letting him sleep there to rest up, but when Sam is sleeping, they handcuff him to the bed so he can't escape. They also put something in the soup to make him sleep, according to another child being held captive. Nick and Rachel are both cannibals, and are eating the children as to not get infected.
Near the end of the book, when Small Sam, Rhiannon and The Kid attempt to escape from being eaten by him. He and Rachel chase the trio through the train station. Rhiannon sacrifices herself to save The Kid and Small Sam. Eventually, Small Sam and the kid lead Nick out into the open. Rachel stays inside the train station, because she knows what will happen if she goes out into the sunlight.
Nick knocks out The Kid and fights Small Sam. Nick comes dangerously close to beheading Sam, but then he realises that, because he has neglected eating children and is out in the open, the Disease begins to infect him. As the fight continues, Nick's throat tightens and boils begin to grow across his skin, robbing him of his ability to breathe, and move independently. Nick is finally killed when, because of the magnitude to which he receives the Disease, his body decomposes and explodes.
