Beverley had expected little from an appeal to this man's pity, but the coincidence of Heron's desire for the pearls was so strange that it ought to mean something. It seemed terrible that such a chance should be wasted. Could she persuade Roger to let her give up the pearls? O'Reilly would look at the wonderful things and report upon their beauty. The Herons might be tempted to treat with her. In any case, the scheme was worth the trial.
Silently she went to the door that she had closed, and peeped into Sister Lake's room. It was no surprise to her that Clodagh should have vanished. That was part of the plan. Her exclamation was for O'Reilly's benefit.
"The child's gone!" she cried. "That means she's feeling better. She must be in my room—or in my boudoir. Will you come with me? We'll look for her. It will be on your way out."
O'Reilly followed into the hall. Beverley, thinking quickly, went to the door of her own special sitting room, which adjoined her bedroom. A backward glance told her that the man had stopped facing the vestibule which gave exit from the flat. "Wait one moment," she said. "I'll see where Clodagh is." As she touched the door of the boudoir she was surprised to find it yielding before she turned the handle. This was odd, because she remembered shutting it the last time she came out. She had left the room only at the moment when O'Reilly brought in the half-fainting girl; and she had been particular to close the door because of the pearls. She had placed them on a table in the boudoir, ready for the pearl-stringer. Not that she feared their being stolen! Her own maid had been sent out for the afternoon. Two of the other servants had been given a holiday. Only the butler, the cook, and his assistant were at home, and all three had been in Roger's employ for years. They were above suspicion, and besides, they knew nothing of the pearls. Not a soul knew, save herself, Roger, Clo, and now O'Reilly. Roger had started off in his car before she brought the pearls from her bedroom into the boudoir. Who, then, had opened the door? Perhaps, after all, Clo had not dared attempt the second adventure. Perhaps she was still in the flat, and for some reason to be explained later, had taken refuge in the boudoir?
A glance, however, showed that the girl was not there. The electric light flashed upon a room untenanted. There was the magnificent but broken rope in its case, wound in gleaming, concentric circles, the unstrung pearls retrieved from the floor grouped together on the purple cushion. The door stood open between boudoir and bedroom. Beverley thought that this had been shut also, though she was not sure. "Clo!" she called softly. There was some slight sound, or she imagined it. Quickly she went to the bedroom door, and peeped in, flooding the place with light. Clo was not to be seen. Turning off the electricity again Beverley went out to O'Reilly in the hall.
"Come with me one moment," she said. "I've something to show you."
O'Reilly hesitated.
"Is your friend there? Does she wish to speak to me?" he asked.
"Come and see," Beverley persisted. She led the way into the boudoir, and reluctantly her companion crossed the threshold. Mrs. Sands pointed to the pearls. "I wanted so much to show them to you. See how wonderful they are! Mr. Heron's so proud of his wife. I could arrange some plan, I'm sure, if—if——"
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.
