For Fear of Little Men

"There are places in the world that are seemingly infested by a genius loci or worse. Places where nothing lives and nothing grows; for those that foolishly investigate such sites, death, or worse, awaits. There is such a place in North Wales, shunned by locals for three thousand years. Something is there, something old and evil. Is it this something that is responsible for events taking place across the world? A breakout of food poisoning, the death of a Soviet defector at the Berlin Wall, crazed outbreaks of violence throughout the U.K.? It’s up to Sir Marcus Levin and his wife Tania to undo the Gordian Knot of this riddle while there’s still time... Will they succeed against this seemingly ancient and unstoppable evil?" -- goodreads.com
