I did something truly shocking today... ...I bought a Christmas present... and it isn't even the 20th of December yet!  Anyway, a book has just been published that I know would be of interest to my brother-in-law. My wife and I were both thinking at the same time that it would be of interest to him as we watched a piece on TV about it last night. I work near the biggest bookshop in the city, so I went in and bought it. I know, I know, it is over three months too early to do anything like this, but this piece of insanity is done now.
