"You surprise me, Herr Foligno."

"I suppose so, and I owe you an explanation of my request. Herr Franz Schorn is my bitter enemy and I have never concealed my dislike of him. You were a witness yesterday evening of my quarrel with Captain Pollenz and my clerk. Precisely on this account I do not wish to include in my official paper a suspicion which I myself hold to be entirely groundless. I promise you that I will neglect nothing that will lead to the discovery of the murderer, that I will investigate every step which Herr Schorn has taken to-day, and will have him watched by a thoroughly competent detective. If he is guilty, I shall discover his guilt; but I do not believe he is so, and because I am his foe I will not attach any suspicion to him which, while the true murderer remains undiscovered, might ruin his life, merely because at the time of the murder he had been seen near the scene of the crime. Promise me, Herr Professor, that you will tell no one at present of your meeting with Franz Schorn. Should there be other and more important grounds for suspecting him, I shall request you to give me your account officially."

I pressed the Judge's hand cordially, and joyfully gave him the promise for which he asked. How unjustly I had judged this man! How I had misunderstood him! I was ashamed of the reluctance I had felt to tell him of my meeting with Franz Schorn.

"I must now make out a short official account of your information," the District Judge continued. "You can hardly believe how difficult this is for me. Your account has agitated me so profoundly that I can scarcely control myself. I was very familiar with old Pollenz. He had indeed many disagreeable qualities. Toward others he was often hard and unyielding, but I never had anything to complain of in his behaviour to me. He has often shown me favours. He was indeed almost a friend, and now I must prepare a paper which shall show him to be the victim of a horrible crime, which I must take the first steps to investigate. It must be done. It is my duty. In spite of the pain which my right hand gives me in writing, I will do it immediately."

He took a sheet of paper; pens and ink were at hand, and seated himself on the sofa behind the large table to write. His hand could not have been very painful, for it did not prevent his writing swiftly and clearly. Now and then, without interrupting his writing, he addressed some brief, leading question to me, and in scarcely ten minutes the paper was finished. He read it aloud to me. It was wonderfully concise and clear, without saying one word too much or too little, and I signed it without an alteration. After he had added his own signature, he said, "I must now beg you, Herr Professor, to accompany me to the Lonely House. I shall immediately summon my assistant, as well as the District Physician and the captain of gendarmes, to inspect the premises. You, too, Herr Professor, must be present. You must testify that nothing in the house has been altered in your absence. This is important for further investigation. Can I count upon you!"

"Most certainly."

"Then pray hold yourself in readiness. In half an hour, at the latest, I shall have notified the other gentlemen. The time of waiting, if I may advise you, should be employed by you in strengthening yourself with food and drink. Yon may not feel the need of refreshment at present, but we have some sad hours before us."

How kind and thoughtful! I certainly had cause to ask pardon in my heart of the District Judge for the prejudice he had created.
