The baron's room, which was on the top floor, was in a state to defy description. Not even in the great war have I seen a more complete shambles. Nothing had been touched; all remained just as the chambermaid had found it a half-hour since. Tables and chairs lay shattered on the floor, and the furniture, floor and walls were spattered with blood. The baron, a tall, muscular man in life, lay in the middle of the room, a fearful spectacle. His skull had been cleft to the brows, a deep gash under his left armpit had shorn through his ribs, and his left arm hung by a shred of flesh. The cold bearded face was set in a look of indescribable horror. "Some heavy, curved weapon must have been used," said Gordon, "something like a saber, wielded with terrific force. See where a chance blow sank inches deep into the window-sill. And again, the thick back of this heavy chair has been split like a shingle. A saber, surely." "A tulwar," I muttered, somberly. "Do you not recognize the handiwork of the Central Asian butcher? Yar Khan has been here." "The Afghan! He came across the roofs, of course, and descended to the window-ledge by means of a knotted rope made fast to something on the edge of the roof. About one-thirty the maid, passing through the corridor, heard a terrific commotion in the baron's room--smashing of chairs and a sudden short shriek which died abruptly into a ghastly gurgle and then ceased--to the sound of heavy blows, curiously muffled, such as a sword might make when driven deep into human flesh. Then all noises stopped suddenly. "She called the manager and they tried the door and, finding it locked, and receiving no answer to their shouts, opened it with the desk key. Only the corpse was there, but the window was open. This is strangely unlike Kathulos' usual procedure. It lacks subtlety. Often his victims have appeared to have died from natural causes. I scarcely understand." "I see little difference in the outcome," I answered. "There is nothing that can be done to apprehend the murderer as it is." "True," Gordon scowled. "We know who did it but there is no proof--not even a finger print. Even if we knew where the Afghan is hiding and arrested him, we could prove nothing--there would be a score of men to swear alibis for him. The baron returned only yesterday. Kathulos probably did not know of his arrival until tonight. He knew that on the morrow Rokoff would make known his presence to me and impart what he learned in northern Asia. The Egyptian knew he must strike quickly, and lacking time to prepare a safer and more elaborate form of murder, he sent the Afridi with his tulwar. There is nothing we can do, at least not until we discover the Scorpion's hiding-place; what the baron had learned in Mongolia, we shall never know, but that it dealt with the plans and aspirations of Kathulos, we may be sure." * * * * *
