"Certain. When I have time I will tell you everything. But not now. And that man must never know that you have been near the house to-night, not so much for your sake as for the sake of your friend David Steel. Now I can see the Providence behind it all. Hatherly, tell me that you forgive me before the others come back." "My darling, I cannot see how you could have acted otherwise." Enid turned towards him with a great glad light in her eyes. She said nothing, for the simple reason that there was nothing to say. Hatherly Bell caught her in his strong arms, and she swayed to reach his lips. In that delicious moment the world was all forgot. But not for long. There was a sudden rush and a tumble of feet on the stairs, there was a strange voice speaking hurriedly, then the drawing-room door opened and Margaret Henson came in. She was looking wild and excited and talked incoherently. An obviously professional man followed her. "My dear madam," he was saying, "I have done all I can. In the last few days I have not been able to disguise from myself that there was small hope for the patient. The exhaustion, the shock to the system, the congestion, all point to an early collapse." "Is my sister so much worse, Dr. Walker?" Enid asked, quietly. "She could not be any worse and be alive," the doctor said. "Unless I am greatly mistaken the gentleman behind you is Mr. Hatherly Bell. I presume he has been called in to meet me? If so, I am sincerely glad, because I shall be pleased to have a second opinion. A bad case of"--here followed a long technical name--"one of the worst cases I have ever seen." "You can command me, Enid," Bell said. "If I can." "No, no," Enid cried. "What am I saying? Please to go upstairs with Martin." Bell departed, wonderingly. Enid flew to the door and out into the night. She could hear Henson cursing and shouting, could hear the snarling clamour of the dogs. At the foot of the drive she paused and called Steel softly by name. To her intense relief he came from the shadow. "I am here," he cried. "Do you want me?" "Yes, yes," Enid panted. "Never more were your services needed. My sister is dying; my sister must--die. And Hatherly Bell is with her, and--you understand?" "Yes," said David. A vivid flash of understanding had come to him. "Bell shall do as I tell him. Come along." "Hold him up, dear doggies," Enid murmured. "Hold him up and I'll love both of you for ever." CHAPTER XV A MEDICAL OPINION David Steel followed his guide with the feelings of the man who has given himself over to circumstances. There was a savour of nightmare about the whole thing that appealed distinctly to his imagination. The darkness, the strange situation, the vivid streaks of the crimson blinds--the crimson blind that seemed an integral part of the mystery--all served to stimulate him. The tragic note was deepened by the whine and howling of the dogs. "There is a man over there," David whispered.
