"Have no fear, Mr. Bennett. Dr. Watson is the very soul of discretion, and I can assure you that this is a matter in which I am very likely to need an assistant."
"As you like, Mr. Holmes. You will, I am sure, understand my having some reserves in the matter."
"You will appreciate it, Watson, when I tell you that this gentleman, Mr. Trevor Bennett, is professional assistant to the great scientist, lives under his roof, and is engaged to his only daughter. Certainly we must agree that the Professor has every claim upon his loyalty and devotion. But it may best be shown by taking the necessary steps to clear up this strange mystery."
"I hope so, Mr. Holmes. That is my one object. Does Dr. Watson know the situation?"
"I have not had time to explain it."
"Then perhaps I had better go over the ground again before explaining some fresh developments."
"I will do so myself," said Holmes, "in order to show that I have the events in their due order. The Professor, Watson, is a man of European reputation. His life has been academic. There has never been a breath of scandal. He is a widower with one daughter, Edith. He is, I gather, a man of very virile and positive, one might almost say combative, character. So the matter stood until a very few months ago.
"Then the current of his life was broken. He is sixty-one years of age, but he became engaged to the daughter of Professor Morphy, his colleague in the chair of Comparative Anatomy. It was not, as I understand, the reasoned courting of an elderly man, but rather the passionate frenzy of youth, for no one could have shown himself a more devoted lover. The lady, Alice Morphy, was a very perfect girl both in mind and body, so that there was every excuse for the Professor's infatuation. Nonetheless, it did not meet with full approval in his own family."
"We thought it rather excessive," said our visitor.
"Exactly. Excessive and a little violent and unnatural. Professor Presbury was rich, however, and there was no objection upon the part of the father. The daughter, however, had other views, and there were already several candidates for her hand, who, if they were less eligible from a worldly point of view, were at least more of an age. The girl seemed to like the Professor in spite of his eccentricities. It was only age which stood in the way.
