The official turned to Katrina. "Will you state again, please, the time that you say the Karl Armstadt you knew disappeared?"
Katrina quite accurately named the date at which the man whose identity I had assumed had been called to the potash mines.
"Very well," said the official, taking up the sheet of paper, "here we have the list of missing men for four years compiled from the weighers' records. There is not recorded here the disappearance of a single chemist during the whole period. If another man than a chemist should try to step into a chemist's shoes, he would have a rather difficult time of it." The official laughed as if he thought himself very clever.
"But that man is not Karl Armstadt," cried Katrina in a wavering voice. "Do you think I would not know him when every night for--"
"Shut up," said the official, "and get out of here, and if I hear anything more of this matter I shall subtract your credit."
Katrina, now whimpering, was led from the room. The official beamed upon Capt. Grauble and myself. "Do you see," he said, "how perfectly our records take care of these crazy accusations? The black haired one is evidently touched in the head with jealousy, and now that she has chanced upon you, she makes up this preposterous story, which might cause you no end of annoyance, but here we have the absolute refutation of the charge. Before a man can step into another's shoes, he must step out of his own. Murdered bodies can be destroyed, although that is difficult, but one man cannot be two men!"
We left the official chuckling over his cleverness.
"The Keeper of Records was wise after his kind," mused Grauble, "but it never occurred to him that there might be chemists in the world who are not registered in the card files of Berlin."
Grauble's voice sounded a note of aloofness and suspicion. Had he penetrated my secret? Did I dare make full confession? Had Grauble given me the least encouragement I should have done so, but he seemed to wish to avoid further discussion and I feared to risk it.
My hope of a fuller understanding with Grauble seemed destroyed, and we soon separated without further confidences.
