ACKNOWLEDGEMENTS

A special mention must go to my good friend Zoe Trodd who shared her research, her time, insights and support as I wrote Agent 6, particularly with relation to the subject of American Communism, and including guided tours of the relevant locations in New York. Zoe has been an invaluable source of information – she’s a wonderful friend, and a brilliant mind.

I have been lucky to have the support of two great editors, Mitch Hoffman at Grand Central Publishing, and Suzanne Baboneau at Simon & Schuster UK. I’d also like to thank Felicity Blunt at Curtis Brown for all her help with this novel and Robert Bookman at CAA – I owe a great deal to both of them. And finally I’d like to thank Ben Stephenson for his support over the past two years.
