He remained standing, and shook his head at the chair.

"I've no time to sit down," he said, "but I thought I'd just look in as
I passed."

There was a note in his voice that made me look at him sharply.

"Have you discovered anything?" I asked.

He nodded his head slowly.

"Not very much, Mr. Merton, but something."

Yet there seem to be a hint of jubilation in his eye.

"Won't you tell the other terrier?"

His face relaxed a little and for a moment I half thought he was going to confide in me, and then he said,

"It's a little too soon to say much. But I'm on the track of something, I don't mind admitting; something pretty surprising too, if it's the right track. Possibly I may be able to tell you more to-night. Could you come out this evening with me if I needed you?"
