John Verdon is the author of the Dave Gurney series of thrillers, international bestsellers published in more than two dozen languages: Think of a Number, Shut Your Eyes Tight, Let the Devil Sleep, Peter Pan Must Die, Wolf Lake, and On Harrow Hill. Before becoming a crime fiction writer, John had two previous careers — as an advertising creative director and a custom furniture maker. He currently lives with his wife Naomi in the rural mountains of upstate New York — raising chickens, tending the garden, mowing the fields, and devising the intricate plots of the Gurney novels.
