Bourgonef's remark had been but too sagacious. The police were hoplessly baffled. In all such cases possible success depends upon the initial suggestion either of a motive which leads to a suspicion of the person, or of some person which leads to a suspicion of the motive. Once set suspicion on the right track, and evidence is suddenly alight in all quarters. But, unhappily, in the present case there was no assignable motive, no shadow darkening any person. An episode now came to our knowledge in which Bourgonef manifested an unusual depth of interest. I was led to notice this interest, because it had seemed to me that in the crime itself, and the discussions which arose out of it, he shared but little of the universal excitement. I do not mean that he was indifferent--by no means; but the horror of the crime did not seem to fascinate his imagination as it fascinated ours. He could talk quite as readily of other things, and far more readily of the French affairs. But on the contrary, in this new episode he showed peculiar interest. It appeared that Lehfeldt, moved, perhaps, partly by a sense of the injustice which had been done to Kerkel in even suspecting him of the crime, and in submitting him to an examination more poignantly affecting to him under such circumstances than a public trial would have been under others; and moved partly by the sense that Lieschen's love had practically drawn Kerkel within the family--for her choice of him as a husband had made him morally, if not legally, a son-in-law; and moved partly by the sense of loneliness which had now settled on their childless home,--Lehfeldt had in the most pathetic and considerate terms begged Kerkel to take the place of his adopted son, and become joint partner with him in the business. This, however, Kerkel had gently yet firmly declined. He averred that he felt no injury, though great pain had been inflicted on him by the examination. He himself in such a case would not have shrunk from demanding that his own brother should be tried, under suspicions of similar urgency. It was simple justice that all who were suspected should be examined; justice also to them that they might for ever clear themselves of doubtful appearances. But for the rest, while he felt his old affectionate respect for his master, he could recognize no claim to be removed from his present position. Had she lived, said the heartbroken youth, he would gladly have consented to accept any fortune which her love might bestow, because he felt that his own love and the devotion of a life might repay it. But there was nothing now that he could give in exchange. For his services he was amply paid; his feelings towards Lieschen's parents must continue what they had ever been. In vain Lehfeldt pleaded, in vain many friends argued. Franz remained respectfully firm in his refusal.
