“Why, yes, sir; of course I couldn’t say so surely. I thought he was reading or writing, but oh, dear Lord! there he was this morning, nearly twelve hours later, in just the same position.” Johann shivered at the thought that he might have seen his master sitting at his desk, already a corpse.
“He must have been dead when you came home. Don’t you think the sound of that shot would have wakened you?”
“Yes, sir, I think likely, sir,” murmured Johann. “But if the murderer could get into the house, how could he get into the apartment?”
“There must have been a third key of which you knew nothing,” answered Horn, turning to Muller again. “It’s stranger still how Fellner could have been shot, for the window-shutters were fastened and quite uninjured, and both doors were locked on the inside.”
As he said these words, Horn looked sharply at his subordinate; but Muller’s calm face did not give the slightest clue to his thoughts. The experienced police commissioner was pleased and yet slightly angered at this behaviour on the part of the detective. He knew that it was quite possible that Muller had already formed a clear opinion about the case, and that he was merely keeping it to himself. And yet he was glad to see that the little detective had apparently learned a lesson from his recent mistake concerning the death of Mrs. Kniepp—that he had somewhat lost confidence in his hitherto unerring instinct, and did not care to express any opinion until he had studied the matter a little closer. The commissioner was just a little bit vain, and just a little bit jealous of this humble detective’s fame.
Muller shrugged his shoulders at the remark of his superior, and the two men stood silent, thinking over the case, as the Chief of Police appeared, accompanied by the doctor, a clerk, and two hospital attendants. The chief commissioner received the report of what had been discovered, while the corpse was laid on a bier to be taken to the hospital.
Muller handed the commissioner his hat and cane and helped him into his overcoat. Horn noticed that the detective himself was making no preparations to go out. “Aren’t you coming with us?” he asked, astonished.
“I hope the gentlemen will allow me to remain here for a little while,” answered Muller modestly.
“But you know that we will have to close the apartment officially,” said Horn, his voice sharpening in his surprise and displeasure.
“I do not need to be in these rooms any longer.”
