The Dietz answered quickly. Mr. Justin O'Reilly was still staying in the hotel, but he had gone out. Tears started to Clo's eyes. She was trapped now, and must summon Beverley to get the pearls. She had not the Sands' 'phone number, and must ask Central to call the Park Avenue apartment. When she had done this, silence fell. But it was only for a moment. Clo stood, with her ear at the receiver still, when a loud bang on the door made her jump as though she had been shot. The door knob turned. "You little devil!" shrilled Kit's voice. "You--thief! I know you're there. Wait till I catch you!" "Hello!" spoke a foreign-sounding voice through the 'phone--the voice of a woman. "Hello! Yes, this is Mrs. Sands' flat. Mr. and Mrs. Sands are not at home." "When will they be back?" asked Clo. "I don't know that," answered the cold voice of Anna Schultz. "It may be a long time." The girl had an instant of despair, but she was not yet beaten. As Kit pounded furiously on the door, Clo called up the jeweller where Ellen Blackburne was employed. Ellen had been in but gone out again; but, oh, she had just returned. She would step to the 'phone. A moment later Ellen's calm "Hello" seemed to travel to her from a far-distant, peaceful world. "This is Clo," replied the girl, conscious that voices outside the door ceased their clamour in order that ears might hear her message. "Yes, I said Clo! For God's sake get into a taxi and rush to the number and street I'm going to give you. Listen! Don't stop to ask questions. When you get here, you don't need to come in. I'll drop something out of the window. You can guess what. I'll expect you quick. Good-bye!" "I heard you!" shrieked Kit. "_I_ can guess, too! You've stolen my pearls, and you think you'll pass 'em on to some other thief. But you won't, you devil! We'll have this door down in five minutes." Clo went to the window, rolled up the blind, and raised the sash. "Why won't you let me call the police?" she heard Mrs. Mac asking. "I tell you it's the only thing. I----" "She won't let you do it because she stole the pearls herself," cried Clo, darting across the room to put her lips to the keyhole. "And that's not all she's afraid of." "I'll kill you when I get my hands round your throat," Kit screamed her down. "I won't be the first you've killed. Take care!" Clo retorted, and was then stung with regret for her boldness. There would be no mercy for her now from Kit or Churn when the door gave way. They would know that she'd been the woman at the telephone masquerading as Kit. But, if only Miss Blackburne came first, before they broke in, she didn't much care. With the pearls safe, she could fight for herself.
