My younger brother and I used to regularly borrow this spooky picture book in early-mid 90s (could also be from the 80s). I remember rich illustrations and a main character with an Ichabod Crane nervousness about him. Can’t remember any of the plot except that at the climax of the book he is in a dark church and he believes there are ghosts all around. My brother’s memory is that the main character was an organist/pianist and that another character dresses up as a ghost and chases him off. I don’t *think* this is a version of Sleepy Hollow. But given how vague my memory is, anything is possible. Even if it is, I would love to figure out which version it is specifically. My brother and I have been trying to figure this out for years.
