by Sir Arthur Conan Doyle
When I'm ill I don't really want to be challenged or stimulated. I'd rather have something familiar or at least predictable. So during my latest cold I pulled the Sherlock Holmes books off the shelf. In fact, this is all five books of short stories in one large volume, so it wasn't a great choice - reading such a heavy book in bed probably wasn't ideal for someone feeling weakened anyway!
Still, the stories are always enjoyable and met my needs perfectly well. Given how old they are the stories are remarkably undated.
