Dark Mirror, by Barry Maitland

Creepy. Poison kind of freaks me out a little. Lots of stuff about libraries. I'm wondering if it really is this easy to look at the borrowing records of people in UK libraries? Cuz--and this is key--this book would NEVER work in the US because we don't keep a list of what people use, nor will librarians voluntarily (i.e., without a warrant/subpoena) give up to the police any requests made by patrons.
