sound, it was worth taking seriously. This realisation brought great uneasiness and grief to the doctor’s heart, for he had grown fond of both of the men on whom terrible suspicion was cast by such an authority. Muller himself was uneasy, but the gloom that had hung over him for the past day or two had vanished. The impenetrable darkness that had surrounded the mystery of the pastor’s murder had gotten on his nerves. He was not accustomed to work so long over a problem without getting some light on it. But now, since the chance watching of the spinning top in the street had given him his first inkling of the trail, he was following it up to a clear issue. The eagerness, the blissful vibrating of every nerve that he always felt at this stage of the game, was on him again. He knew that from now on what was still to be done would be easy. Hitherto his mind had been made up on one point; that one man alone was concerned in the crime. Now he understood the possibility that there might have been two, the harmless mechanician who fancied himself a dangerous murderer, and the handsome young giant with the evil eyes. The two men stood looking at each other in a silence that was almost hostile. Had this stranger come to disturb the peace of the refuge for the unfortunate and to prove that Dr. Orszay, the friend of all the village, had unwittingly been giving shelter to such criminals? “Shall we go now?” asked the detective finally. “If you wish it, sir,” answered the doctor in a tone that was decidedly cool. Muller held out his hand. “Don’t let us be foolish, doctor. If you should find yourself terribly deceived, and I should have been the means of proving it, promise me that you will not be angry with me.” Orszay pressed the offered hand with a deep sigh. He realised the other’s position and knew it was his duty to give him every possible assistance. “What is there for me to do now?” he asked sadly. “You must see that all the patients are shut up in their cells so that the other attendants are at our disposal if we need them. Varna’s room has barred windows, I suppose?” “Yes.”
