Trail of Cthulhu: Midnight Sub Rosa

The diary of Ezekiel de la Poer, a colonial-era French necromancer hanged for child-murder in 1736 was stolen at the home of an emeritus professor in the small town of Rosa, Alabama. His house lives in the eaves of a forest of white ash. Can the Investigators find the book before its thief becomes something else entirely? This scenario comes from Out of the Woods, an anthology of forest themed Trail of Cthulhu scenarios.
