.. "THE MARTIAN AMBASSADOR - Complete Edition" by Alan Baker
I've read the first chapter and it looks to be a very intriguing and well-written VSF detective book. Should also have some potential for VSF gaming.
Available on-line from Completely Novel. You can read it online free and then buy it should you wish. At £6.99 I'll be buying it in the printed version, as I can't be doing with this new-fangled e-book nonsense
