White Corridor by Christopher Fowler

Oh, Christopher Fowler, you disappoint me. Your elderly detectives Arthur Bryant and John May are so wonderful on their own -- why must you introduce a second storyline which includes a peek into a serial killer's mind? I know this may sound cranky, but I would much rather spend time with my friends Bryant and May than with some serial killer I hardly even know. So, I did the only thing I could -- I quickly skimmed all the serial killer sections, and only slowed down when I got to a Bryant and May section. The descriptions of the two detectives and their interactions with each other are priceless. (At one point, the technologically inept Bryant asks May whether he can find out some information "on that interweb thingie.")
