"You can't stop me now! I've completed the task that was set me all those centuries ago. Nothing can stop me now."Mr. Charles is a jewel thief by profession, as is his chauffeur and cohort-in-crime, Dawkins. Together, the two embarked upon a notorious string of robberies (being exceedingly selective, in what they stole) of British stately homes - including Creighton-Ward Manor, which drew the notice of its owner, the aristocratic (and International Rescue agent) Lady Penelope Creighton-Ward.
But Mr. Charles has a far-loftier target in mind: nothing less than the theft of the British Crown Jewels! He and Dawkins infiltrate the historic Tower of London to steal them - but their plans are ultimately thwarted, by Penelope and her own chauffeur (and fellow IR agent), Parker, along with International Rescue aquanaut Gordon Tracy.
In defeat, Mr. Charles revealed the motivation driving his crime spree: to avenge his ancestors, the Grandvilles family, who'd themselves once owned valuable jewelry - including the Crown Jewels. But Penelope's ancestors, who were loyal to King Richard the Lionheart, had reclaimed them.
Proving that what goes around, indeed, comes around, Penelope surreptitiously recorded his confession, using a special recorder (provided by Brains) that only picked up male voices; and both Mr. Charles and Dawkins were arrested for their crimes. "Your family would have been proud of you," she says, in bidding him farewell, "they finished up in gaol too, I believe..."
