“As long as she was on the scene he could not take any action without a horrible exposure of the woman whom he loved.  But the instant that she was gone he realised how crushing a misfortune this would be for you, and how all-important it was to set it right.  He rushed down, just as he was, in his bare feet, opened the window, sprang out into the snow, and ran down the lane, where he could see a dark figure in the moonlight.  Sir George Burnwell tried to get away, but Arthur caught him, and there was a struggle between them, your lad tugging at one side of the coronet, and his opponent at the other.  In the scuffle, your son struck Sir George and cut him over the eye.  Then something suddenly snapped, and your son, finding that he had the coronet in his hands, rushed back, closed the window, ascended to your room, and had just observed that the coronet had been twisted in the struggle and was endeavouring to straighten it when you appeared upon the scene.”

“Is it possible?” gasped the banker.

“You then roused his anger by calling him names at a moment when he felt that he had deserved your warmest thanks.  He could not explain the true state of affairs without betraying one who certainly deserved little enough consideration at his hands.  He took the more chivalrous view, however, and preserved her secret.”

“And that was why she shrieked and fainted when she saw the coronet,” cried Mr. Holder.  “Oh, my God! what a blind fool I have been!  And his asking to be allowed to go out for five minutes!  The dear fellow wanted to see if the missing piece were at the scene of the struggle.  How cruelly I have misjudged him!”

“When I arrived at the house,” continued Holmes, “I at once went very carefully round it to observe if there were any traces in the snow which might help me.  I knew that none had fallen since the evening before, and also that there had been a strong frost to preserve impressions.  I passed along the tradesmen’s path, but found it all trampled down and indistinguishable.  Just beyond it, however, at the far side of the kitchen door, a woman had stood and talked with a man, whose round impressions on one side showed that he had a wooden leg.  I could even tell that they had been disturbed, for the woman had run back swiftly to the door, as was shown by the deep toe and light heel marks, while Wooden-leg had waited a little, and then had gone away.  I thought at the time that this might be the maid and her sweetheart, of whom you had already spoken to me, and inquiry showed it was so.  I passed round the garden without seeing anything more than random tracks, which I took to be the police; but when I got into the stable lane a very long and complex story was written in the snow in front of me.
