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."

"It is certainly darker than the rest."

"So it is." He took the two pieces carrying the puttied hole, threw the rest on the heap, and addressed the landlady. "The Mr. Harvey Challitt who occupied this room before Mr. Kingscote, and who got into trouble for forgery, was the Mr. Harvey Challitt who was himself robbed of diamonds a few months before on a staircase, wasn't he?"

"Yes, sir," Mrs. Lamb replied in some bewilderment. "He certainly was that, on his own office stairs, chloroformed."

"Just so, and when they marched him away because of the forgery, Mr. Kingscote changed into his rooms?"

"Yes, and very glad I was. It was bad enough to have the disgrace brought into the house, without the trouble of trying to get people to take his very rooms, and I thought——"

"Yes, yes, very awkward, very awkward!" Hewitt interrupted rather impatiently. "The man who took the rooms on Monday, now—you'd never seen him before, had you?"

"No, sir."

"Then is that anything like him?" Hewitt held a cabinet photograph before her.

"Why—why—law, yes, that's him!"

Hewitt dropped the photograph back into his breast pocket with a contented "Um," and picked up his hat. "I think we may soon be able to find that young gentleman for you, Mrs. Lamb. He is not a very respectable young gentleman, and perhaps you are well rid of him, even as it is. Come, Brett," he added, "the day hasn't been wasted, after all."

We made towards the nearest telegraph office. On the way I said, "That puttied-up hole in the piece of wood seems to have influenced you. Is it an important link?"

"Well—yes," Hewitt answered, "it is. But all those other pieces are important, too."

"But why?"

"Because there are no holes in them." He looked quizzically at my wondering face, and laughed aloud. "Come," he said, "I won't puzzle you much longer. Here is the post-office. I'll send my wire, and then we'll go and dine at Luzatti's."

He sent his telegram, and we cabbed it to Luzatti's. Among actors, journalists, and others who know town and like a good dinner, Luzatti's is well known. We went upstairs for the sake of quietness, and took a table standing alone in a recess just inside the door. We ordered our dinner, and then Hewitt began:

"Now tell me what your conclusion is in this matter of the Ivy Cottage murder."

"Mine? I haven't one. I'm sorry I'm so very dull, but I really haven't."

"Come, I'll give you a point. Here is the newspaper account (torn sacrilegiously from my scrap-book for your benefit) of the robbery perpetrated on Harvey Challitt a few months before his forgery. Read it."

"Oh, but I remember the circumstances very well. He was carrying two packets of diamonds belonging to his firm downstairs to the office of another firm of diamond merchants on the ground-floor. It was a quiet time in the day, and half-way down he was seized on a dark landing, made insensible by chloroform, and robbed of the diamonds—five or six thousand pounds' worth altogether, of stones of various smallish individual values up to thirty pounds or so. He lay unconscious on the landing till one of the partners, noticing that he had been rather long gone, followed and found him. That's all, I think."

"Yes, that's all. Well, what do you make of it?"

"I'm afraid I don't quite see the connection with this case."

"Well, then, I'll give you another point. The telegram I've just sent releases information to the police, in consequence of which they will probably apprehend Harvey Challitt and his confederate, Henry Gillard, alias Jones, for the murder of Gavin Kingscote. Now, then."

"Challitt! But he's in gaol already."

"Tut, tut, consider. Five years' penal was his dose, although for the first offence, because the forgery was of an extremely dangerous sort. You left Chelsea over three years ago yourself, and you told me that his difficulty occurred a year before. That makes four years, at least. Good conduct in prison brings a man out of a five years' sentence in that time or a little less, and, as a matter of fact, Challitt was released rather more than a week ago."

"Still, I'm afraid I don't see what you are driving at."

"Whose story is this about the diamond robbery from Harvey Challitt?"

"His own."

"Exactly. His own. Does his subsequent record make him look like a person whose stories are to be accepted without doubt or question?"

"Why, no. I think I see—no, I don't. You mean he stole them himself? I've a sort of dim perception of your drift now, but still I can't fix it. The whole thing's too complicated."

"It is a little complicated for a first effort, I admit, so I will tell you. This is the story. Harvey Challitt is an artful young man, and decides on a theft of his firm's diamonds. He first prepares a hiding-place
