“She was trembling with excitement, and her state communicated itself in some degree to me, so that I was scarcely able to think coherently. But there certainly seemed to be plausibility in her scheme; at the worst, it would be better than shooting the man outright. But would the recovery of the papers put an end to Slurk’s persecution of Kate as well as of her father? Would not his power over her remain?

“‘But we can have him imprisoned then, you see,’ was her answer to my objection; ‘and for fear of that, he would never dare to trouble me again. He would have been in prison long ago but for the papers.’

“‘It certainly seems a good plan,’ I said, after a confused attempt to turn the matter over in my mind. ‘We’ll ask your father’s opinion to-morrow.’

“‘Oh, he must know nothing of it!’ she exclaimed, with a gesture of vehement dissent. ‘He would betray it. You don’t know how—what a power that villain has over him. Slurk treats him like a child when they are alone. No, Tom; we must do it all ourselves, or it will fail. Only when it is done will dear papa get back his courage.’

“I knew more about how Mr. Birchmore was treated by his valet in private than Kate was aware; but I made no allusion to this. The more I reflected upon the enterprise, the more inclined I was to assent to it. It was wild, fantastic, unconventional; but it had important practical merits nevertheless. Moreover, it possessed the powerful recommendation (as I deemed it) of allowing for a fair man-to-man struggle between Slurk and myself. I was to overpower him by main strength; and from what I had observed of the fellow, I fancied he would be able to make resistance enough to save my self-respect. On the other hand, he might be able to do more than this; and if the worst came to the worst, of course I might be compelled to maim him with my revolver. But altogether, the prospect kindled my imagination; I was stimulated by the thought of distinguishing myself by my personal prowess before my mistress’s eyes, in conflict with her dastardly oppressor. And as I looked at her standing there before me, so lovely and so full of courageous fire, I said to myself that no knight of yore ever did battle in the lists for a worthier lady-love!

“However, I realised that this was neither the place nor the hour to enter upon a detailed discussion of our plans. Every moment that Kate remained with me increased her peril, especially if, as she seemed to think was the case, Slurk had despatched her thither. As to his motive in so doing, I had no difficulty in forming an opinion. There was little doubt that he meant to use her as an unconscious cat’s-paw to steal the diamonds, as, before, to purloin the papers compromising her father. Had I been asleep, the device could hardly have failed of success. But as Kate seemed herself not to suspect the real nature of her involuntary errand, I would not additionally distress her by alluding to it; it was enough that it furnished me with a sufficient pretext, had others been wanting, for inflicting chastisement on the valet.

“Kate said, in answer to my inquiry as to the proposed time of our starting on the picnic expedition the next day, that it would probably be about eleven in the forenoon; we would, therefore, have ample time to settle the particulars of our scheme before the hour of action arrived. At parting, she clung to me with peculiar tenderness; nor had I ever loved her so well as that moment, when I looked forward to liberating her for ever from the evil spell that had been blighting her young life.

“After she had gone, I had the curiosity to examine the bolt on the door. The explanation of its mysterious opening proved simple enough. The screws whereby the socket of the bolt had been fastened to the door-frame had been removed, and the holes so enlarged that they could be slipped in and out without difficulty. Socket and screws had then been replaced, so that the bolt could be shot as readily as before. But the security was only an illusion; for, the latch being turned, a slight push would bring away the socket and screws attached to the bolt; and thus the supposed means of safety be ingeniously used to disguise the real absence thereof.

“It occurred to me next morning that, considering the nature of the work that was cut out for me, it might be prudent to depart from my usual custom by leaving the diamonds at home in Christina’s charge, as she had herself suggested; and I took the earliest opportunity of mentioning this proposal to Kate. To my surprise she at once expressed a decided dissent from the arrangement, and indeed seemed so much perturbed by it, that I at once relinquished the idea. But I begged her to tell me the reasons of her objection.
