In this case there was exactly the same impenetrable mystery and absence of motive which had characterized the murder of Professor von Hopstein. In the dead man’s pocket there was found a note-book containing a considerable sum in gold and several very valuable bills, but no attempt had been made to rifle him. Supposing that anyone to whom he had lent money (and this was the first idea which occurred to the police) had taken this means of evading his debt, it was hardly conceivable that he would have left such a valuable spoil untouched. Schiffer lodged with a widow named Gruga, at 49 Marie Theresa Strasse, and the evidence of his landlady and her children showed that he had remained shut up in his room the whole of the preceding day in a state of deep dejection, caused by the suspicion which the populace had fastened upon him. She had heard him go out about eleven o’clock at night for his last and fatal walk, and as he had a latch-key she had gone to bed without waiting for him. His object in choosing such a late hour for a ramble obviously was that he did not consider himself safe if recognized in the streets. The occurrence of this second murder so shortly after the first threw not only the town of Buda-Pesth, but the whole of Hungary, into a terrible state of excitement and even of terror. Vague dangers seemed to hang over the head of every man. The only parallel to this intense feeling was to be found in our own country at the time of the Williams murders described by De Quincey. There were so many resemblances between the cases of Von Hopstein and of Schiffer that no one could doubt that there existed a connection between the two. The absence of object and of robbery, the utter want of any clew to the assassin, and, lastly, the ghastly nature of the wounds, evidently inflicted by the same or a similar weapon, all pointed in one direction. Things were in this state when the incidents which I am now about to relate occurred, and in order to make them intelligible I must lead up to them from a fresh point of departure. Otto von Schlegel was a younger son of the old Silesian family of that name. His father had originally destined him for the army, but at the advice of his teachers, who saw the surprising talent of the youth, had sent him to the University of Buda-Pesth to be educated in medicine. Here young Schlegel carried everything before him, and promised to be one of the most brilliant graduates turned out for many a year. Though a hard reader, he was no bookworm, but an active, powerful young fellow, full of animal spirits and vivacity, and extremely popular among his fellow-students.
