Yet--was it a strange voice? As it went on to ask: "Is this Mr. Peterson?" Clo had a strong impression that she had heard the voice before. Assuredly it was not the one which had talked to "Kit," but it sounded astonishingly familiar. Though she could not yet identify the tones recognition was only a question of instants. "This is Mr. Peterson's room," she replied. "He is--here. He wishes me to speak for him." "I had better tell you before we go further, then, that I'm talking for Mr. John Heron. When you have explained that, Mr. Peterson will decide whether he'd rather come to the 'phone and attend to the business himself." Clo was glad of the pause. "John Heron!" That was the man Peterson had mentioned during her second conversation with him. He had said that Roger Sands was "working for John Heron" when Roger and Beverley met in the train; and she--Clo--had heard the name with a queer thrill which she could not understand. So far as she knew, it was strange to her: yet she seemed to have heard it in dreams--sad dreams, where someone had sobbed in the dark. Through the strenuous adventures which had kept body and brain busy the girl had recalled it again and again, since the moment when the name had fallen from Peterson's lips. She had wondered if she would ever have the "cheek" to ask Angel who was John Heron. Whoever he might be, John Heron was in some way concerned with Beverley's secret, or Peterson would not have spoken his name in that connection. She answered quietly: "Mr. Peterson allows me to go on speaking for him." "Very well," returned the voice. "Mr. Peterson called Mr. Heron up not long ago, to say he could sell him a rope of fine pearls for Mrs. Heron, at a low price. He'd heard, it appears, that Mr. Heron wished to buy pearls, and he suggested an appointment for to-night. Mr. Heron did not receive this message himself; he was indisposed at the time it came, and Mrs. Heron took it, but was unable to answer for her husband. He asks me to say, in his name, that if Mr. Peterson has some particularly fine pearls to dispose of, he'll be pleased to look at them, not to-night, but to-morrow morning about ten o'clock, at his hotel, the Dietz." "The Dietz!" cried Clo. "Now I know who's speaking to me. You're Justin O'Reilly!" Inadvertently she had kept her lips at the receiver. The cry had flown to the man who held the line. "And you're my girl burglar! By Jove, I thought I knew that voice! Are you in the pearl business, too? Has Mrs. Sands commissioned you and some fellow called Peterson to sell her pearls to Mrs. Heron? Now I begin to see light! She tried to make a bargain with me over those pearls. I refused in Heron's name and my own. What's her game now, when there's nothing left to bargain for, and you've sent the papers back?"
