“It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. Now, I knew that it was not you who had brought it down, so there only remained your niece and the maids. But if it were the maids, why should your son allow himself to be accused in their place? There could be no possible reason. As he loved his cousin, however, there was an excellent explanation why he should retain her secret — the more so as the secret was a disgraceful one. When I remembered that you had seen her at that window, and how she had fainted on seeing the coronet again, my conjecture became a certainty.

“And who could it be who was her confederate? A lover evidently, for who else could outweigh the love and gratitude which she must feel to you? I knew that you went out little, and that your circle of friends was a very limited one. But among them was Sir George Burnwell. I had heard of him before as being a man of evil reputation among women. It must have been he who wore those boots and retained the missing gems. Even though he knew that Arthur had discovered him, he might still flatter himself that he he was safe, for the lad could not say a word without compromising his own family.

“Well, your own good sense will suggest what measures I took next. I went in the shape of a loafer to Sir George’s house, managed to pick up an acquaintance with his valet, learned that his master had cut his head the night before, and, finally, at the expense of six shillings, made all sure by buying a pair of his cast-off shoes. With these I journeyed down to Streatham and saw that they exactly fitted the tracks.”

“I saw an ill-dressed vagabond in the lane yesterday evening,” said Mr. Holder.

“Precisely. It was I. I found that I had my man, so I came home and changed my clothes. It was a delicate part which I had to play then, for I saw that a prosecution must be avoided to avert scandal, and I knew that so astute a villain would see that our hands were tied in the matter. I went and saw him. At first, of course, he denied everything. But when I gave him every particular that had occurred, he tried to bluster and took down a life-preserver from the wall. I knew my man, however, and I clapped a pistol to his head before he could strike. Then he became a little more reasonable. I told him that we would give him a price for the stones he held 1000 pounds apiece. That brought out the first signs of grief that he had shown. ‘Why, dash it all!’ said he, ‘I’ve let them go at six hundred for the three!’ I soon managed to get the address of the receiver who had them, on promising him that there would be no prosecution. Off I set to him, and after much chaffering I got our stones at 1000 pounds apiece. Then I looked in upon your son, told him that all was right, and eventually got to my bed about two o’clock, after what I may call a really hard day’s work.”

“A day which has saved England from a great public scandal,” said the banker, rising. “Sir, I cannot find words to thank you, but you shall not find me ungrateful for what you have done. Your skill has indeed exceeded all that I have heard of it. And now I must fly to my dear boy to apologize to him for the wrong which I have done him. As to what you tell me of poor Mary, it goes to my very heart. Not even your skill can inform me where she is now.”

As he came near the little market–place he bethought himself of the Christmas–tree candles. He did not intend to trouble himself. And yet, when he glanced in passing into the sweet–shop window, and saw it bare as a board, the very fact that he probably could not buy the things made him hesitate, and try.

“Have you got any Christmas–tree candles?” he asked as he entered the shop.

“How many do you want?”

“A dozen.”

“Can’t let you have a dozen. You can have two boxes—four in a box— eight. Six–pence a box.”

“Got any holders?”

“Holders? Don’t ask. Haven’t seen one this year.”

“Got any toffee—?”

“Cough–drops—two–pence an ounce—nothing else left.”

“Give me four ounces.”

He watched her weighing them in the little brass scales.

“You’ve not got much of a Christmas show,” he said.

“Don’t talk about Christmas, as far as sweets is concerned. They ought to have allowed us six times the quantity—there’s plenty of sugar, why didn’t they? We s’ll have to enjoy ourselves with what we’ve got. We mean to, anyhow.”

“Ay,” he said.

“Time we had a bit of enjoyment, THIS Christmas. They ought to have made things more plentiful.”

“Yes,” he said, stuffing his package in his pocket.

The war had killed the little market of the town. As he passed the market place on the brow, Aaron noticed that there were only two miserable stalls. But people crowded just the same. There was a loud sound of voices, men’s voices. Men pressed round the doorways of the public–houses.

But he was going to a pub out of town. He descended the dark hill. A street–lamp here and there shed parsimonious light. In the bottoms, under the trees, it was very dark. But a lamp glimmered in front of the “Royal Oak.” This was a low white house sunk three steps below the highway. It was darkened, but sounded crowded.

Opening the door, Sisson found himself in the stone passage. Old Bob, carrying three cans, stopped to see who had entered—then went on into the public bar on the left. The bar itself was a sort of little window–sill on the right: the pub was a small one. In this window– opening stood the landlady, drawing and serving to her husband. Behind the bar was a tiny parlour or den, the landlady’s preserve.

“Oh, it’s you,” she said, bobbing down to look at the newcomer. None entered her bar–parlour unless invited.

“Come in,” said the landlady. There was a peculiar intonation in her complacent voice, which showed she had been expecting him, a little irritably.

He went across into her bar–parlour. It would not hold more than eight or ten people, all told—just the benches along the walls, the fire between—and two little round tables.
