The place we entered was a comfortably furnished bachelor's apartment. Books and papers were littered about giving evidence of no disturbance since the sudden leaving of the occupant. Immensely relieved I sat down in an upholstered chair while the nurse scurried about and put the place in order. "You feel quite at home?" he asked as he finished his task. "Quite," I replied, "things are coming back to me now." "You should have been sent home sooner," he said. "I wished to tell the chief as much, but I am only a second year interne and it is forbidden me to express an original opinion to him." "I am sure I will be all right now," I replied. He turned to go and then paused. "I think," he said, "that you should have some notice on you that when you do go out, if you become confused and make mistakes, the guards will understand. I will speak to Lieut. Forrester, the Third Assistant, and ask that such a card be sent you." With that he took his departure. When he had gone I breathed joyfully and freely. The rigid face and staring eye that I had cultivated relaxed into a natural smile and then I broke into a laugh. Here I was in the heart of Berlin, unsuspected of being other than a loyal German and free, for the time at least, from problems of personal relations. I now made an elaborate inspection of my surroundings. I found a wardrobe full of men's clothing, all of a single shade of mauve like the suit I wore. Some suits I guessed to be work clothes from their cheaper texture and some, much finer, were evidently dress apparel. Having reassured myself that Armstadt had been the only occupant of the apartment, I turned to a pile of papers that the hospital attendant had picked up from the floor where they had dropped from a mail chute. Most of these proved to be the accumulated copies of a daily chemical news bulletin. Others were technical chemical journals. Among the letters I found an invitation to a meeting of a chemical society, and a note from my tailor asking me to call; the third letter was written on a typewriter, an instrument the like of which I had already discovered in my study. This sheet bore a neatly engraved head reading "Katrina, Permit 843 LX, Apartment 57, K Street, Level of the Free Women." The letter ran: "Dear Karl: For three weeks now you have failed to keep your appointments and sent no explanation. You surely know that I will not tolerate such rude neglect. I have reported to the Supervisor that you are dropped from my list." So this was Katrina! Here at last was the end of the fears that had haunted me. ~2~
