A door slammed, and Beverley's sentence broke off with a gasp. Mechanically she shut down the cover of the velvet case. If Roger had come back; if, after all, he had only pretended to go for the pearl-stringer! She dared not guess what he would think at finding O'Reilly with her in his house. Too well she remembered the day of their one quarrel, when he had brought up this man's name in connection with Clo's, when he had accused her of crying it out in her sleep. "Mr. O'Reilly," she said, very quietly, "that may be my husband coming home. If it is, you will have to meet him. It can't be avoided. But I should like to speak to him first, if you will wait in this room for a moment." Without giving him time to answer she ran out. Minutes passed. Justin heard voices, women's voices. One, it seemed to him, was raised in anger. After all, it couldn't be Sands who had come! O'Reilly grew impatient, and fumbling for his watch he found it gone. Great Scott! Stolen! He remembered a certain small key attached to the chain. In a flash of enlightenment the whole plot mapped itself out before his eyes. Furious, his impulse was to dash from the room and denounce the chief culprit. But Beverley Sands' appeal to his chivalry stopped him like a chain round his feet. Now she called his name, and he opened the door. "It was my friend's nurse who came in," she said. "She threatens to leave at once. I must talk with her, try to soothe her down before my husband comes. He hasn't arrived, after all--and may not for a long time. But the way I felt when I thought he was here, shows me I oughtn't to keep you. Tell me once and for all before you go, now you've seen the pearls; is there any hope?" "None whatever," O'Reilly cut her short. "I'm going, Mrs. Sands. You need have no fear of me where your husband's concerned, though I understand now exactly why I was brought here, why I was kept till you were afraid to keep me longer. Your little friend is as smart at picking pockets as she is at acting. Again, I congratulate you upon her. But the effort's going to be wasted. Good-night." Beverley stood still, and let him go. She had no answer to make. Precisely what he meant by his accusation she did not understand, but she knew that, while she detained him, Clo had indeed dared the great adventure. For a moment Beverley thought of the pearls almost with distaste. That they should come to her to-day, when she cared for nothing in the world but the lost papers, was an irony of fate. She did not return to the boudoir. She forgot the mystery of the open door, and neglected to close it. She was nervously anxious to excuse herself to Sister Lake. Above all, it was her duty to defend Clo. She must confess that it was upon her errand the girl had defied authority. "Please don't blame the child," she pleaded. "She knew I needed something done for me--a thing I couldn't do myself. So she made this sacrifice. You must forgive us both."
