Aftermath

ACKNOWLEDGMENTS

I would like to thank my editor, Patricia Lande Grader, for her help in reshaping the unruly early drafts, and my wife, Sheila Halladay, for her perceptive and helpful comments. Also, many thanks to my agent, Dominick Abel, for all his hard work on my behalf, and to Erika Schmid for her fine copyediting.

As far as research goes, the usual crowd came through: Detective Sergeant Keith Wright, Detective Inspectors Claire Gormley and Alan Young, and Area Commander Philip Gormley. Any mistakes are entirely my own and are, of course, made in the interests of dramatic fiction. Also, thanks to Woitek Kubicki for his advice on Polish names.

A number of books proved invaluable in understanding the “killer couple” phenomenon, and among those to which I owe my greatest debt of gratitude are Emlyn Williams, Beyond Belief; Brian Masters, She Must Have Known; Paul Britton, The Jigsaw Man; Gordon Burn, Happy Like Murderers; and Stephen Williams, Invisible Darkness.
