When he first met her, Tom knew that Clare Galbraith was different from the other women he had met but nothing could have prepared him for what he was to learn after she was murdered. The official police explanation was that she had been killed when a robbery went wrong. Then Mark, a newspaper reporter and friend of Tom's, begins asking questions and Tom starts to realise Clare was not what she had seemed. Not everyone believes Clare was the victim of a mugger but the truth is more fantastic than any of them could have thought.

As Tom and Mark begin a journey to discover what really happened, they find themselves involved in the sinister underworld of MI6 where Clare worked as a code-breaker. They are soon plunged deep into a plot involving secret-agents and terrorists. Asadullah, a fanatical off-shoot of the Taliban, is planning a revenge attack in the UK against the Americans for burning copies of the Qur'an. Without realising it, Tom and Mark become mixed up in this dangerous operation. At the centre of everything is the coded message Clare left behind. Does it contain the answers Tom is looking for and will he ever be able to crack it?

This exciting, fast-paced story is both a murder-mystery and an action-packed thriller that will keep the reader guessing until the very end!
