I'd like to thank the following people for their help with this book. Firstly, best buddy and fellow author Mark Morris for persuading me to have a go at Torchwood, my editor Steve Tribe for making the whole process painless, and Sam and Andy for letting me live in their Scottish hideaway while I wrote it. And I couldn't go without thanking Jimmy George for his constant and boundless enthusiasm for all things Doctor Who/Torchwood-related!
