I examined the broken panels with some care, having half a notion to attempt to deduce something from them myself, if possible. But I could deduce nothing. The beading had been taken out, and the panels, which were thick in the centre but bevelled at the edges, had been removed and split up literally into thin firewood, which lay in a tumbled heap on the hearth and about the floor. Every panel in the room had been treated in the same way, and the result was a pretty large heap of sticks, with nothing whatever about them to distinguish them from other sticks, except the paint on one face, which I observed in many cases had been scratched and scraped away. The rug was drawn half across the hearth, and had evidently been used to deaden the sound of chopping. But mischief—wanton and stupid mischief—was all I could deduce from it all.
Mr. Jones's cousin, it seemed, only Sarah had seen, as she admitted him in the evening, and then he was so heavily muffled that she could not distinguish his features, and would never be able to identify him. But as for the other one, Mrs. Lamb was ready to swear to him anywhere.
Hewitt was long in coming, and internal symptoms of the approach of dinner-time (we had had no lunch) had made themselves felt before a sharp ring at the door-bell foretold his arrival. "I have had to wait for answers to a telegram," he said in explanation, "but at any rate I have the information I wanted. And these are the mysterious panels, are they?"
Mrs. Lamb's true opinion of Martin Hewitt's behaviour as it proceeded would have been amusing to know. She watched in amazement the antics of a man who purposed finding out who had been splitting sticks by dint of picking up each separate stick and staring at it. In the end he collected a small handful of sticks by themselves and handed them to me, saying, "Just put these together on the table, Brett, and see what you make of them."
I turned the pieces painted side up, and fitted them together into a complete panel, joining up the painted design accurately. "It is an entire panel," I said.
"Good. Now look at the sticks a little more closely, and tell me if you notice anything peculiar about them—any particular in which they differ from all the others."
I looked. "Two adjoining sticks," I said, "have each a small semi-circular cavity stuffed with what seems to be putty. Put together it would mean a small circular hole, perhaps a knot-hole, half an inch or so in diameter, in the panel, filled in with putty, or whatever it is."
"A knot-hole?" Hewitt asked, with particular emphasis.
"Well, no, not a knot-hole, of course, because that would go right through, and this doesn't. It is probably less than half an inch deep from the front surface."
"Anything else? Look at the whole appearance of the wood itself. Colour, for instance."
