My thanks are long overdue to Cynthia Good, my editor from the beginning of the series. I must also thank my agent, Dominick Abel, for his advice and encouragement. This book in particular could not have been completed without the help of many people, all generous with their time and expertise. My thanks go especially to Keith Wright of Nottingham CID, both detective and novelist; Douglas Lucas, Director of the Center for Forensic Sciences, Toronto; Mario Possamai for his book, Money on the Run; Ken McFarland, Chartered Accountant; John Picton, journalist; and to Rick Blechta for putting me right about violists. Any errors are entirely my own and were made purely in the interests of dramatic fiction.
