The Turn of the Screw by Henry James

I read this novel in early November, but it would have been great for Halloween. Because the author isn't completely explicit with details, he builds suspense and leaves the reader wondering about the exact nature of the  ghost and its interaction with the children. I enjoyed The Turn of the Screw and The Woman in White for similar reasons, in part because they rely on suspense and ambiguity to keep the reader psychologically off balance. I recommend this book for readers who enjoy mystery and suspense, possibly even psychological horror.
