Fleeing unfavorable regulation at home, American millionaire King Kerry and other American robber barons begin buying up London real estate and important London-based businesses, much to the dismay of their competitors and the people of the city. As his empire expands, Kerry is bedeviled by a mysterious enemy troubled by a dark secret from a past romance.
Along the way we meet some good, honest people whom he brings into the fold and assists them to a better life, while dealing admirably with the criminals and near-criminals who are attracted to his money. This book is one of the most popular novels of Edgar Wallace, and has been translated into several other languages around the world.
