“Now, my dear Hopkins, draw up and warm your toes,” said he. “Here’s a cigar, and the doctor has a prescription containing hot water and a lemon, which is good medicine on a night like this. It must be something important which has brought you out in such a gale.”

“It is indeed, Mr. Holmes. I’ve had a bustling afternoon, I promise you. Did you see anything of the Yoxley case in the latest editions?”

“I’ve seen nothing later than the fifteenth century to-day.”

“Well, it was only a paragraph, and all wrong at that, so you have not missed anything. I haven’t let the grass grow under my feet. It’s down in Kent, seven miles from Chatham and three from the railway line. I was wired for at 3:15, reached Yoxley Old Place at 5, conducted my investigation, was back at Charing Cross by the last train, and straight to you by cab.”

“Which means, I suppose, that you are not quite clear about your case?”

“It means that I can make neither head nor tail of it. So far as I can see, it is just as tangled a business as ever I handled, and yet at first it seemed so simple that one couldn’t go wrong. There’s no motive, Mr. Holmes. That’s what bothers me - I can’t put my hand on a motive. Here’s a man dead - there’s no denying that - but, so far as I can see, no reason on earth why anyone should wish him harm.”

Holmes lit his cigar and leaned back in his chair.

“Let us hear about it,” said he.

“I’ve got my facts pretty clear,” said Stanley Hopkins. “All I want now is to know what they all mean. The story, so far as I can make it out, is like this. Some years ago this country house, Yoxley Old Place, was taken by an elderly man, who gave the name of Professor Coram. He was an invalid, keeping his bed half the time, and the other half hobbling round the house with a stick or being pushed about the grounds by the gardener in a Bath chair. He was well liked by the few neighbours who called upon him, and he has the reputation down there of being a very learned man. His household used to consist of an elderly housekeeper, Mrs. Marker, and of a maid, Susan Tarlton. These have both been with him since his arrival, and they seem to be women of excellent character. The professor is writing a learned book, and he found it necessary, about a year ago, to engage a secretary. The first two that he tried were not successes, but the third, Mr. Willoughby Smith, a very young man straight from the university, seems to have been just what his employer wanted. His work consisted in writing all the morning to the professor’s dictation, and he usually spent the evening in hunting up references and passages which bore upon the next day’s work. This Willoughby Smith has nothing against him, either as a boy at Uppingham or as a young man at Cambridge. I have seen his testimonials, and from the first he was a decent, quiet, hard-working fellow, with no weak spot in him at all. And yet this is the lad who has met his death this morning in the professor’s study under circumstances which can point only to murder.”

The wind howled and screamed at the windows. Holmes and I drew closer to the fire, while the young inspector slowly and point by point developed his singular narrative.
