He looked trustworthy as well as grateful. Kit and Churn were winding their way among the tables. Clo pushed after them. O'Reilly was not on the stairs, nor was he visible in the dull restaurant above. He had the all-important envelope, it was true, and she could not guess who had returned it in a way to make him suppose it came from her. O'Reilly was, however, an honourable man, and he had promised to be "on Mrs. Sands' side." In the circumstances she saw only one course, and regretfully, even fearfully, took it. When Kit and Churn walked out into the street she walked after them, a few paces behind.

Clo had been gone precisely four minutes when O'Reilly tore downstairs burning to apologize and explain. Mrs. Denham had said that her husband was out, but she knew where he was, and would 'phone; if he—O'Reilly—would hold the line she'd have an answer "in no time." Presently he had been rewarded by "getting" Denham, who, on hearing that he was urgently wanted, promised to cut short some work he was doing late at the office, and taxi to Krantz's. This was good news, and O'Reilly was sure Clo would think it had been worth waiting for. He could not believe his eyes when he saw the deserted table. What could have happened to the girl?

He stood forlornly for a moment, staring round the room. As his eyes searched vainly, the waiter who had served him came hurrying up.

"The young lady's gone, sare. She had to go—very sorry. She left me dis to give you when you come back. She pay de bill, sare, but I keep de table for you. You not finish your supper."

O'Reilly had a stab of violent resentment against Clo. But the thought had only to pass through his brain to be rejected. The girl was a strange girl, audacious and unscrupulous in her loyalty to Mrs. Sands; but she could not have told her story in a way to impress its truth upon him unless she had been sincere.

"The young lady didn't give you any other message?" he asked.

"No, sare. She was in much hurry. But I see her mark on a piece of paper," the waiter replied. "Maybe she write you a note."

O'Reilly reflected. Which should he do, look for a message in the pocket of the coat Clo had left, or dash upstairs and find out which way she had gone? It was almost certain that he would now gain nothing by the latter course.

O'Reilly sat down at the table, in the chair where he had sat before. He found the one pocket in the brown coat, and in that pocket Kit's jet and steel bag. There was nothing else there, so he opened the bag cautiously in case some of Kit's friends had arrived. As he did so, the folded programme dropped out.
