Although my name alone appears on the title-page there were many others who made significant contributions to Agatha Christie: Murder in the Making.
As reflected in the Dedication, my gratitude to Mathew Prichard and his wife, Lucy, is boundless. Without their contribution Agatha Christie: Murder in the Making would not exist.
My editors, David Brawn and Steve Gove.
My brother and sister-in-law, Brendan and Virginia, for my home-from-home.
Joseph and Francis, who helped with the proof-reading.
Patricia, Noel, Brian and Ann Donnelly, hosts par excellence.
Robyn Brown, National Trust General Manager of Greenway House, where it all began.
Dr Robin Whelpton for his advice on matters chemical.
Elaine Wiltshire for double-checking.
David, Daniel and Pavla of Goldsboro Books.
