Maynard's House

Maynard Whittier died in Vietnam and he left his cabin in Maine to his buddy Austin Fletcher. This is an oldy but goody that got reissued by Paperbacks from Hell and I was into this....until I wasn't.
My notes:
Austin has a death walk to town. The cabin has “noises”, the rocking chair creaks on its own, phantom dogs. There's a devil's rock out back and a witch tree on the property. Yes, please.
And then we meet the young girl and the story tanks into a pervy dream. Isolated men in cabins will be boys? Right? Gross.
Needed more witch.
