The actual name of the book is 'The Dead Mountaineer's Inn.' What is it with American journalists that they feel it's OK to just change the titles of things to make a snappy headline? I've never seen this behavior in any other country's media. I find it incredibly disrespectful.
It's like a nickname, you refer to a long title with the most descriptive word in it. However, when a book is obscure, this practice does it a disservice.
I've seen this more commonly when a writer has already written the full title earlier in the article. It does seem strange and unhelpful to do it in a headline about an obscure (to the audience) book.
