FOR MY PARENTS
John and Margaret Barclay Lloyd

Special thanks are for Colin, Emily, and Joan, and for Pat Kennedy, Emmet Robbins, Nada Coniç, Norma Rowen, and Alan Koval. Pierre Berton encouraged me to write this book when I had just begun work on it, and so did all the staff of CBC Radio’s Morningside, especially Don Harron, Richard Handler, and Peter Gzowski. Vesna Vukov kindly undertook to check the chemistry sections. I would also like to thank my editors, Ramsay Derry and Sarah Reid, and Jan Walter at McClelland and Stewart.
