This is a hard book to review. It’s beautifully written, thoughtful and very creepy. Narratively, it’s deceptively sprawling for such a short work, covering the ground of a much larger book. It goes everywhere and nowhere, which might be a problem if the other elements of the books weren’t so well done. 
The story is simple and very similar to Theodore Roszak’s much longer ‘Flicker’. The lead character watches an obscure, unsettling film and then spends the rest of the book trying to find out more about its director. ‘All the Witnesses Are Gone’ is much more unsettling. There’s something in Lane’s writing that really gets under your skin and I suspect it’s a book that will linger with me longer than I’d like it to.
