If you like spy thrillers you will almost certainaly love this book. As well as trying to stop a terrorist attack, Liz Carlyle must find an IRA mole (who infiltrated MI5, but was never activated.)
The characters are great and the story cracks along at a terrific pace. There are the usual twists and turns, and although I did guess who the mole was about half way through, there was always the chance that I was wrong (!) and it did nothing to spoil my enjoyment of the book.
Rimington also adds in some nice touches. Even characters who are only bit part players are well drawn and we find out small details about their lives and why they were in that place at that time.
If this is the kind of thing you usually enjoy then buy it! Safe houses, surveillance techniques, the inner workings of the terrorist mind, IRA informers.....this book has it all.
