Book three in the Mallory Cash trilogy.

Will Mallory Cash be the first thief in history to breach The Tower of London?

Mallory Cash is back from the dead - and her enemies are closing in.

When Sam flies to London to find her, Mallory realises there's only one way to save them both. Eve is on her trail, Trafford's spies are everywhere, and the price of survival is unthinkable: Mallory must deliver the Diamond Crown in exchange for their lives.

But the Tower of London has never been breached. When her father arrives, claiming he's there to help, Mallory knows the stakes have never been higher. What follows is a breathless chase through London and a daring plan to escape to Australia, with MI5 and Mallory's enemies in hot pursuit.
