Berkley S1709 (1969)
Dashing young Roderick Kinsmere went up to London to claim his inheritance, left his belongings at his fathers favorite inn, and went out to see the town. He never did get back to his room, and the next time he laid eyes on his possessions, they were in a totally unexpected setting.
Just one of the reasons for the upheaval in Kinsmere's life was the fact that he was wearing a remarkable sapphire ring. It was the cause of his being swept up in court intrigue, murderous plots, and a wild chase that came to an exciting climax in the middle of the English Channel!
