In a contrasting report, historian Richard Kurin speculated that the "theft" of the French Crown Jewels was in fact engineered by the revolutionary leader Georges Danton as part of a plan to bribe an opposing military commander, Duke Karl Wilhelm of Brunswick. When under attack by Napoleon in 1805, Karl Wilhelm may have had the French Blue recut to disguise its identity; in this form, the stone could have come to Britain in 1806, when his family fled there to join his daughter Caroline of Brunswick. Although Caroline was the wife of the Prince Regent George (later George IV of the United Kingdom), she lived apart from her husband, and financial straits sometimes forced her to quietly sell her own jewels to support her household. Caroline's nephew, Duke Karl Friedrich, was later known to possess a blue diamond which was widely thought to be another piece of the French Blue. This smaller diamond's present whereabouts are unknown, and the recent CAD reconstruction of the French Blue fits too tightly around the Hope Diamond to allow for the existence of a sister stone of that size.
