In the man Hawkins, once a game-keeper of Sir Burnham's, I found an instrument ready to my hand. I closed the Park to the public and took all those precautions for preserving my secret which prudence dictated: this at the cost of a reputation in Upper Crossleys which few men would have survived, but which troubled me not at all, since it left me undisturbed to those studies which to me were everything. The death of Sir Burnham, however, had raised a new danger; for in the person of Sir Marcus Coverly, the heir, I perceived a formidable enemy, who because of his wealth might redeem Friar's Park, and, because of the fact that he belonged to a cadet line, might care nothing for the skeleton in Sir Burnham's cupboard. I have said that science is callous, and I admit that it needed little prompting from Nahémah to urge me to take the next step. It is worthy of note, however, from a scientific point of view, that whilst I was prompted by motives of expediency, she was actuated solely by a lust to destroy everything that bore the name of Coverly. My experiments for some time past had been directed to the discovery of new instruments of warfare. Particularly I had addressed myself to the preparation of a _gas_ which should possess the peculiar properties of _hlangkûna_, and by inhalation affect the lung tissues, thus producing instantaneous results. In this I had succeeded a short time prior to Sir Burnham's death, and one of the future belligerents had approached me. For the purpose of carrying out experiments, a specially designed gun was brought from Essen and installed in a secluded part of the Park. Artillery specialists carried out a number of tests with shells of various patterns; but because I bluntly declined to divulge the formula for the making of "L.K. Vapor" (so I had named it) until substantial guarantees were given, negotiations were broken off. I retained, however, the model howitzer as well as a number of special light shells. The gun was one of extraordinary accuracy, and it was possible, given suitable weather conditions, mechanically to train it upon a given target and without any preliminary "searching" to score a certain hit. I caused the piece to be mounted on the top platform of the tower at Friar's Park, and having completed those mathematical calculations with the result of which Mr. Addison has since become familiar, I awaited the return of the new baronet from Russia. Shortly after his arrival, I invited him to visit Upper Crossleys.
