I was privileged to visit two laboratories with BSL4 facilities. At the Canadian Science Center for Animal and Human Health in Winnipeg, Manitoba, I was helped by Stefan Wagener, Laura Douglas, and Kelly Keith; and at the Health Protection Agency in Colindale, London, by David Brown and Emily Collins. Further advice on BSL4 laboratories and procedures came from Sandy Ellis and George Korch.
On security and biosecurity I was advised by Keith Crowdy, Mike Bluestone, and Neil McDonald. For insight into possible police responses to biohazards, I talked to Assistant Chief Constable Norma Graham, Superintendent Andy Barker, and Inspector Fiona Barker, all of the Central Scotland Police in Stirling.
On gambling I spoke to Anthony Holden and Daniel Meinertzhagen, and I was permitted to read the typescript of David Anton's book Stacking the Deck: Beating America 's Casinos at Their Own Game.
Many of the above experts were located for me by Daniel Starer of Research for Writers in New York City.
For comments on drafts of the book, I'm grateful to my editors Leslie Gelbman, Phyllis Grann, Neil Nyren, and Imogen Tate; to my agents Al Zuckerman and Amy Berkower; to Karen Studsrud; and to my family, especially Barbara Follett, Emanuele Follett, Greig Stewart, Jann Turner, and Kim Turner.
