When Professor Goodman discovers a method of creating flawless diamonds at almost no cost, it is much more than a scientific curiosity—especially to the members of the Metropolitan Diamond Syndicate, who determine to stop this threat to their healthy profits. But their plans backfire when the man they recruit to keep the Professor’s discovery a secret turns out to be the world’s greatest villain. Only one man can stop the ensuing intrigue, kidnappings, plotting and murder: Bulldog Drummond. Yet even he is pushed to the limit when he faces his nemesis in the waters off the south coast.
Gripping and thrilling, this is the third of Bulldog Drummond’s contests with the master-criminal Carl Peterson. But is it the last?
