Hall, as related in the seventh volume of this series, entitled, "Dave Porter and His Rivals."
In the present book we find Dave again at school. But the Christmas holidays are at hand and the lad returns home. Here a most mysterious and unlooked-for happening occurs, and Dave's great benefactor, Mr. Wadsworth, is on the verge of ruin because of it. Dave gets a clew to the mystery, and, with his chums, resolves to investigate. He takes a long journey and has a number of stirring adventures, the particulars of which are given in the pages that follow.
When I started this line of books I trusted that Dave might please the boys, but I did not imagine that so many thousands of boys and girls all over the land would clamor as they have for more concerning the doings of my hero. I thank all for their appreciation of my efforts to please them, and I sincerely trust that the reading of this new volume will be a benefit to them.
