I'll happily concede he wrote a werewolf story, but since it was never available as a book, I would not call it a novel.
But after reading Douglas Adam’s, I’m personally hesitant to read unpublished item from any other authors. After finishing The Salmon of Doubt I felt vaguely embarrassed, like I’d barged into his house and found him relaxing on the couch in his boxers. I’m a fan, not a scholar, and there were reasons he wasn’t ready to share the material yet.
If he'd published it himself in that state, I'd have found it embarrassing.
But as a posthumous memorial that I knew from the outset would be unpolished, it was fine and a bit sad knowing it's never be finished.
I think comes down to how well you're able to keep focus on that what you're reading is unfinished, and enjoying the glimpse of something raw.
Not saying that the parts of the story that have been published might not have needed some additional polish, too, but wouldn't the major reason simply be the fact that the whole thing wasn't yet finished as in "the story just stops mid-way"?
We don't know that. It could be a viral laughingstock that becomes the new primary association the public holds for the author (I doubt it, but never say never). If he didn't want it released, I'd say honor his wishes.
Anyway, wait until you find out what he used to do in the bathroom.
