The Bird Witch

From Introduction:

They say William Hart went up into the Mournwoods and no one ever saw him again. But that isn’t really true. Listen. Here in town, he talked to us locals about the old witch stories, so common to this region. He collected those kinds of tales, you see. Even said he’d published a book about them. There used to be so many witches up in the Black Peaks, back in the olden days. Some say there’s still too many! Well, there’s certainly one up there now.
