friends of all whom she met. The years she had spent as her father’s close companion had given her an insight into the ways of unraveling mysteries and the game had fascinated her adventure-loving nature. To the great amusement of the girls she was always trying to imagine a mystery that she might solve it, but in the past year she had twice failed while two of her comrades who had no such ambition had been successful, and so, no wonder was it that Betsy looked forward to the desert as a place where she would surely find a mystery to solve. Virginia, who had been born on the V. M. Ranch, which was twenty miles from the town of Douglas, and who had lived there all her seventeen years, was indeed overjoyed because she was returning to the home she so loved, to her very dear brother Malcolm Davis and to old Uncle Tex, who, when he was younger, had been the foreman of V. M. The father of Barbara Wente had recently purchased the Dartley Ranch which was four miles north of V. M. This he had given to his son Peyton. Barbara had learned that the old house was interesting, but she had never seen it as, with the other girls, she had left almost at once after the deal had been completed, for the school in the east. “What do you think, Virg?” Babs chattered as the four girls with their hats on and their bags ready, sat peering ahead, “Peyton wrote in his very last letter that he hasn’t even opened the old ranch house yet. He is leaving it for us to do.” “I adore old houses,” Betsy began, when Virginia exclaimed as she pointed out the windows. “See that dark hole in the mountain just ahead of us?” The others leaned forward to look. “Oh, good!” Margaret exclaimed. “It’s the last tunnel, and Silver Creek station is just beyond.” Megsy turned toward her adopted sister, a flushed eagerness betraying the excitement she felt. “Just think, Virg, in ten minutes we are to see Malcolm.” Betsy uttered a little excited squeal as the train plunged into the darkness of the tunnel. “Virg, isn’t this a thrilling moment,” Barbara whispered, “not being sure who is to be at the other end?” Sunlight again flashed into the car windows. Virginia stooped and looked out. “There’s the little old station that’s the only house for miles and miles around, but I don’t see anyone on the platform except the old man who lives there. Wonder what has happened?”
