"What smouldering fire of vengeance had suddenly sprung into flame in this passionate Celtic woman's soul when she saw the man who had wronged her--wronged her perhaps far more than we suspected--in her power? Was it a chance that the wood had slipped and that the stone had shut Brunton into what had become his sepulchre? Had she only been guilty of silence as to his fate? Or had some sudden blow from her hand dashed the support away and sent the slab crashing down into its place. Be that as it might, I seemed to see that woman's figure, still clutching at her treasure-trove, and flying wildly up the winding stair with her ears ringing perhaps with the muffled screams from behind her, and with the drumming of frenzied hands against the slab of stone which was choking her faithless lover's life out. "Here was the secret of her blanched face, her shaken nerves, her peals of hysterical laughter on the next morning. But what had been in the box? What had she done with that? Of course, it must have been the old metal and pebbles which my client had dragged from the mere. She had thrown them in there at the first opportunity, to remove the last trace of her crime. "For twenty minutes I had sat motionless thinking the matter out. Musgrave still stood with a very pale face swinging his lantern and peering down into the hole. "'These are coins of Charles I.,' said he, holding out the few which had been left in the box. 'You see we were right in fixing our date for the Ritual.' "'We may find something else of Charles I.,' I cried, as the probable meaning of the first two questions of the Ritual broke suddenly upon me. 'Let me see the contents of the bag which you fished from the mere.' "We ascended to his study, and he laid the débris before me. I could understand his regarding it as of small importance when I looked at it, for the metal was almost black, and the stones lustreless and dull. I rubbed one of them on my sleeve, however, and it glowed afterwards like a spark, in the dark hollow of my hand. The metal-work was in the form of a double ring, but it had been bent and twisted out of its original shape. "'You must bear in mind,' said I, 'that the Royal party made head in England even after the death of the King, and that when they at last fled they probably left many of their most precious possessions buried behind them, with the intention of returning for them in more peaceful times.' "'My ancestor, Sir Ralph Musgrave, was a prominent Cavalier, and the right-hand man of Charles II. in his wanderings,' said my friend. "'Ah, indeed!' I answered. 'Well, now, I think that really should give us the last link that we wanted. I must congratulate you on coming into the possession, though in rather a tragic manner, of a relic which is of great intrinsic value, but of even greater importance as an historical curiosity.' "'What is it, then?' he gasped in astonishment. "'It is nothing less than the ancient crown of the Kings of England.'
