This is another collection of short stories by Edward Phillips Oppenheim, the prolific English novelist who was in his lifetime a major and successful writer of genre fiction including thrillers and spy novels, and who wrote over a 100 of them. He was the self-styled prince of storytellers, generally regarded as the earliest writer of spy fiction as we know it today, and invented the Rogue Male school of adventure thrillers.
This book is a revenge story with each chapter describing how Mannister takes care of the different people who wronged him.
