Interpol have tried and failed to find her. Now the combined forces of Scotland Yard and MI5 must try the impossible to prevent a major international incident. Dominic Elder carries her autograph wherever he goes. Witch is his passion, his obsession. And being retired is no bar to his willingness to restart the hunt. MI5 know that the man who wrote the Witch file is the key to catching their quarry. But the truth isn't easy to spot. And it is only when an MI5 novice and his French counterpart piece together the smallest of clues, that Witch suddenly looks vulnerable . . .
But Bell has never had a challenge like this one. From Arizona to Colorado to the streets of San Francisco during its calamitous earthquake and fire, he pursues what is quickly becoming clear to him is the sharpest criminal mind he has ever encountered, and the woman who seems to hold the key to the bandit's identity. Using science, deduction, and intuition, Bell repeatedly draws near only to grasp at thin air, but at least he knows his pursuit is having an effect.
