Deede Dawson and his unknown companion went on towards the house, and admitted themselves, and as the door closed behind them Clive swung round sharply in the darkness towards Dunn.

“What's it mean?” he muttered in the bewildered and slightly-pathetic voice of a child at once frightened and puzzled. “What for? Why should any one—?”

“It's a long story,” began Dunn, and paused.

He saw that the unexpected confirmation of his warning Clive had thus received from Deede Dawson's own lips had rendered his task of convincing Clive immensely more easy.

What he had wished to say had now at least a certainty of being listened to, a probability of being believed, and there was at any rate, he supposed, no longer the danger he had before dreaded of Clive's going straight with the whole story to Deede Dawson in arrogant disbelief of a word of it.

But he still distrusted Clive's discretion, and feared some rash and hasty action that might ruin all his plans, and allow Deede Dawson time to escape.

Besides he felt that the immediate task before him was to find out who Deede Dawson's new companion was, and, if possible, overhear anything they might have to say to each other.

That, and the discovery of the new-comer's identity, might prove to be of the utmost importance.

“I can't explain now,” he said hurriedly. “I'll see you tomorrow sometime. Don't do anything till you hear from me. Your life may depend on it—and other people's lives that matter more.”

“Tell me who you are first,” Clive said quickly, incautiously raising his voice. “I can manage to take care of myself all right, I think, but I want to know who you are.”
