“I don’t see how a complete stranger could spot at first sight anything that skilled detectives failed to discover after very close examination,” he said coolly. “You’ll have to convince me that it’s something more than mere curiosity on your part before I go any further.”

“And against that there’s such a thing as looking at some object for so long that after a while one doesn’t see it at all. It’s the fresh eye that picks things up. Would it surprise you if I said that you’ve got something close to you at this minute that might be a clue, and you never guess it.”

Martin drew in his breath sharply, but Derrick’s eyes never left the stranger’s face.

“Isn’t that a rather wild shot of yours?”

“It may be, but I’ll risk it. I reckon I’ve sucked in something from the places I’ve been in that helps to get under the skin at times. Getting back to clues, this world is full of clues that go unnoticed just because people don’t know how to look at them. Same thing when you get so used to a thing that you can’t tell whether it’s in the room or not, without making sure. That’s because you don’t hear what it says.”

“Ah,” put in Derrick swiftly, “then you believe that things talk?”

“It’s the only talk worth listening to now and then.”

Derrick’s pulse quickened. “Is that what you depend on in this case?”

The peddler nodded. “Perhaps it would surprise you if I said that something was talking at this very minute, a queer kind of stuff that I only half get.”

Saying this, he lifted his eyes, and sent Derrick an extraordinary look. There was power in it, and a certain mesmeric weight, and in a strange but unmistakable fashion it invited the young man to acknowledge what he himself believed. This look stated very plainly that the stranger saw through Derrick’s camouflage, and also quite understood the present necessity for it; but it suggested, too, that behind the newcomer was an authority that as yet he had no intention to disclose. There were no words in which to phrase what Derrick felt. Presently, and as though to make the thing as easy as possible for the master of Beech Lodge, the little man gave a short laugh.
