From the official Garth Marenghi website...
Bill Chaffe, part-time renegade and full-time cynic, discovers he was born with a third eye, surgically excavated from his skull at birth, and kept by top brass neuro-surgeons in a secret government compound. But are these visions madness or premonitions? Or a state-funded operation to breed an elite race of spies? Or both?
FACTOID: The cover design and book layout is one of the most effective in modern horror. Marenghi famously designs all the covers to his publications: 'I went for simple elegance. My name, Garth Marenghi, embossed in gloss black on a matt black cover - so it looks like the name is coming from the very pits of hell itself. And when you open the cover there's a pop-up eye on a stalk.
Cool... hopefully I'll find the book on Amazon or Abebooks... here is hoping!
*UPDATE* I found out the publisher is Beelzebooks. Maybe this will help.
