What happened to Godfrey Ablewhite?

Godfrey Abelwhite is a barrister involved in social causes. In London, he talks Rachel into accepting his proposal of marriage, but she breaks the engagement. A year after the Diamond is pledged, it is redeemed by a man dressed as a sailor. That man was Godfrey and he was found dead at a lodging house near the wharf. The box which held the Moonstone was empty.
