Publisher's Synopsis
They were dangerous-looking men, thirty of them in all, armed to the teeth. They looked like unscrupulous fellows who would hesitate at no desperate deed. Some of them had bad records, and yet they had served Frank Merriwell faithfully in guarding his mine, the Queen Mystery, against those who tried to wrest it from him by force and fraud. Frank had called these men together, and he now stood on his doorstep in Mystery Valley, Arizona, looking them over. Bart Hodge, Frank's college chum and companion in many adventures, was behind him in the doorway. Little Abe, a hunchback boy whom Merriwell had rescued from ruffians at a mining camp and befriended for some time, peered from the cabin. Merry smiled pleasantly as he surveyed the men. "Well, boys," he said, "the time has come when I shall need your services no longer." Some of them stirred restlessly and looked regretful.
