The plot of the story hinges upon the possession of a valuable bracelet, of diamonds, stolen from a Hindoo idol by a British soldier in India. This bracelet falls into the possession of Colonel Thorndyke, who, shortly afterward, is sent home to England because of his wounds. The secret concerning the bracelet is told to the Colonel's brother, a country squire, and the treasure is left to younger members of the Thorndyke family.
As is well known today, the theft of anything from a Hindoo temple is considered an extraordinary crime in India, and when this occurs it becomes a religious duty for one or more persons to hunt down the thief and bring back the property taken from the heathen god.
The members of the Thorndyke family soon learn that they are being watched. But this is at a time when highwaymen are numerous in this part of England, and they cannot determine whether the work is that of the “knights of the roads” or that of the Lascars after the famous bracelet. A mysterious death follows, and the younger members of the family are almost stunned, not knowing what will happen next. They would give the bracelet up, but do not know where it is hidden, the secret having been in the sole possession of the member now dead. In this quandary the young hero of the tale rises to the occasion and determines to join the London police force and become a detective, with the hope of ultimately clearing up the mystery. Thrilling adventures of a most unusual kind follow, and at last something of the mystery is explained. The bracelet and other jewelry are unearthed, and it is decided to take the bracelet to Amsterdam and offer it to the diamond cutters at that place. But the carrying of the bracelet is both difficult and dangerous. How the mission is brought to a conclusion, and what part the Lascars played in the final adventure, will be found in the pages that follow.
It can truthfully be said that Mr. Henty is easily the most popular of all English story tellers, his books for boys enjoying a circulation of from a hundred and fifty thousand to two hundred and fifty thousand per year. His tales are all clean, and although some are full of exciting situations and thrilling to the last degree, they are of a high moral tone, while the English employed is of the best.
The present story is of peculiar value as giving a good insight into country and town life in England over a hundred years ago, when railways and telegraph lines were unknown and when the “knights of the road” were apt to hold up any stagecoach that happened to come along. It also gives a truthful picture of the dark and underhanded work accomplished at times by those of East Indian blood, especially when on what they consider a religious mission.
