The trouble with moonlight

In the midst of a moonlit safecracking mission, British spy James Locke witnesses a ruby necklace spirited away as if by conjurer's trick. Following the jewels leads him to Lusinda Havershaw, who's inherited the talent of turning invisible in the moonlight--at least, the parts of her that are unclothed. Locke trains Lusinda in espionage, even while he finds her close proximity bewitchingly distracting. And as their mission to track Russian spies grows treacherous, they'll find that the heart behaves even more mysteriously than Lusinda in the moonlight.
