Blue Monday

Acknowledgements

This is the first book of a series, and the start of a new journey for us. We would like to thank Michael Morris, Dr Julian Stern and Dr Cleo Van Velsen for their generous help and advice. They shouldn’t necessarily be held responsible for our interpretation of that help and advice.

Tom Weldon and Mari Evans have been a source of support and loyalty for more years than any of us probably likes to remember; to them and the dynamic team at Penguin, we owe a huge debt of gratitude.

We’re constantly grateful for the unstinting care and support of our agents, Sarah Ballard and Simon Trewin, also of St John Donald and everyone at United Agents. Sam Edenborough and Nicki Kennedy of ILA have protected and looked after us throughout our years of writing together.
