"One moment, sir. I have some sort of recollection, when I was a student at Bonn, hearing of some German doctor who had achieved a marvellous reputation for having effected certain cures in insane cases which had been given up by everyone else." "You mean old Hildebrand of Derrendorf," said the Doctor. "Yes, he was really a wonderful man, and did some extraordinary things. I never met him; but his cases were reported in the medical journals here, and made a great sensation at the time; but that is ten or twelve years ago, and I recollect hearing since that he had retired from practice. I should think by this time he must be dead." "Then there is no hope," said George, sadly. "I fear none," said his father. "If Hildebrand were alive, there would be no chance of his undertaking the case; for if I recollect rightly, he had always determined on retiring from the profession as soon as he had amassed a certain amount of money, which would enable him to pursue his studies in quiet. He was an eccentric genius too--one of the rough-and-ready school, they said, and particularly harsh and unpleasant in his manners. I recollect there was a joke that he frightened people into their wits, as other patients were frightened out of theirs by their doctors; so that he would scarcely do for Miss Annette, even if we could command his services. By-the-way, of course there was no seizure while you were in the house?" "Nothing of the kind. She was, as I said, perfectly calm and tranquil, and wonderfully artless and childlike." "Yes; she remains the ruin of what would have been a most charming creature. That 'little rift within the lute,' as Tennyson has it, has marred all the melody. By-the-way, you said you knew the reason of Mrs. Derinzy's having impressed upon me the necessity of silence in regard to my visits there. What was it?" "There is no secret in it now. Mrs. Derinzy always intended that her son Paul should marry his cousin." "I see it all! An heiress, is she not, to an enormous property? A very good thing for her son." "Ah! that was why, ever since symptoms of the girl's mental malady first began to develop themselves, the boy was kept away at school, even during the holidays, on some pretence or another; and why, since he has been at the Stannaries Office, he has, up to this time, always gone abroad or to stay with some friends on his leave of absence." "Exactly. The secret has been well kept from him. And do you mean to say he does not know it now?" "At this moment he hasn't the least idea of it." "Then your friend is also your rival, my poor George?" "No, indeed. Paul does not care in the least for Annette, and he is deeply pledged in another quarter. It was with a view of aiding him in extricating himself from the engagement which his mother was pressing upon him that he asked me down to the Tower." "As neat a complication as could possibly be," said the Doctor.
