When MI5 Intelligence Officer Liz Carlyle learns from one of her agents that there have been suspicious meetings in the Islamic bookshop where he works, she feels almost instinctively that a terrorist cell is at work. Liz, immediately reports her findings to Charles Wetherby, her superior at MI5, and a surveillance operation is swiftly put into place. So when Wetherby pulls Liz off the case and tasks her to investigate a tip that many years ago a mole was planted in one of the branches of British Intelligence she feels distinctly marginalised. To Liz, the likelihood of a mole seems small, but if Wetherby is right then the potential damage to the Service itself could be immeasurable. In SECRET ASSET, the second Liz Carlyle novel, Stella Rimington once again brings all her experience as a former Director General of MI5 to bear in a truly compelling thriller that takes the reader into a world where no-one can be trusted and nothing is what is seems.
