Kneeling in a muddy field, clutching something soft and blue-black, Marc Hamer vows he will stop trapping moles-forever. In this earnest, understated, and sublime work of nonfiction literature, the molecatcher shares what led him to this strange career: from sleeping among hedges as a homeless teen, to toiling on the railway, to weeding windswept gardens in Wales. Hamer infuses his wanderings with radiant poetry and stark, simple observations on nature's oft-ignored details. He also reveals how to catch a mole-a craft long kept secret by its masters-and burrows into the unusual lives of his muses. Moles, we learn, are colorblind. Their blood holds unusual amounts of carbon dioxide. Their vast tunnel networks are intricate and deceptive. And, like Hamer, they work alone.
