Kyle Murchison Booth, archivist at the Parrington Museum, has heard of Thirdhop Scarp. Everyone has. The house has been notorious ever since the night that homeowner J.A. Cathcart murdered his entire family, and was found cupping the heart of his eldest daughter in his hands as tenderly as he would a wounded bird.
