"Your letter has reached me this moment," the note ran. "It came by your train. I am glad not to have missed you altogether and I hope that you will come to-night. The camel will bring you to the camp and take you back in plenty of time for the mail." After all then the quest had not failed. After all he was to see for himself--what a man could see within two hours, of the inner life of a married couple. Not very much certainly, but a hint perhaps, some token which would reveal to him what it was that had written so much character into Stella Ballantyne's face and driven Jane Repton into warnings and reserve. "I will go at once," said Thresk and his bearer translated the words to the camel-driver. But even so Thresk stayed to look again at the letter. Its handwriting at the first glance, when the unexpected words were dancing before his eyes, had arrested his attention; it was so small, so delicately clear. Thresk's experience had made him quick to notice details and slow to infer from them. Yet this handwriting set him wondering. It might have been the work of some fastidious woman or of some leisured scholar; so much pride of penmanship was there. It certainly agreed with no picture of Stephen Ballantyne which his imagination had drawn. He mounted the camel behind the driver, and for the next few minutes all his questions and perplexities vanished from his mind. He simply clung to the waist of the driver. For the camel bumped down into steep ditches and scuffled up out of them, climbed over mounds and slid down the further side of them, and all the while Thresk had the sensation of being poised uncertainly in the air as high as a church-steeple. Suddenly however the lights of the camp grew large and the camel padded silently in between the tents. It was halted some twenty yards from a great marquee. Another servant robed in white with a scarlet sash about his waist received Thresk from the camel-driver. He spoke a few words in Hindustani, but Thresk shook his head. Then the man moved towards the marquee and Thresk followed him. He was conscious of a curious excitement, and only when he caught his breath was he aware that his heart was beating fast. As they neared the tent he heard voices within. They grew louder as he reached it--one was a man's, loud, wrathful, the other was a woman's. It was not raised but it had a ring in it of defiance. The words Thresk could not hear, but he knew the woman's voice. The servant raised the flap of the tent.
