"Possibly you are thinking of the connection between insanity and phases of the moon?"
"No, I assure you. It was quite a different line of thought. Possibly you can leave your notebook with me and I will check the dates. Now I think, Watson, that our line of action is perfectly clear. This young lady has informed us—and I have the greatest confidence in her intuition—that her father remembers little or nothing which occurs upon certain dates. We will therefore call upon him as if he had given us an appointment upon such a date. He will put it down to his own lack of memory. Thus we will open our campaign by having a good close view of him."
"That is excellent," said Mr. Bennett. "I warn you, however, that the Professor is irascible and violent at times."
Holmes smiled. "There are reasons why we should come at once—very cogent reasons if my theories hold good. To-morrow, Mr. Bennett, will certainly see us in Camford. There is, if I remember right, an inn called the 'Chequers' where the port used to be above mediocrity, and the linen was above reproach. I think, Watson, that our lot for the next few days might lie in less pleasant places."
Monday morning found us on our way to the famous University town—an easy effort on the part of Holmes, who had no roots to pull up, but one which involved frantic planning and hurrying on my part, as my practice was by this time not inconsiderable. Holmes made no allusion to the case until after we had deposited our suit-cases at the ancient hostel of which he had spoken.
"I think, Watson, that we can catch the Professor just before lunch. He lectures at eleven, and should have an interval at home."
"What possible excuse have we for calling?"
Holmes glanced at his notebook.
"There was a period of excitement upon August 26. We will assume that he is a little hazy as to what he does at such times. If we insist that we are there by appointment I think he will hardly venture to contradict us. Have you the effrontery necessary to put it through?"
"We can but try."
