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, White River Burning, and On Harrow Hill. Before becoming a crime fiction writer, Verdon 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.
