“You will tell me if you have any news to-morrow. No doubt you will go to the prison to see James. Oh, if you do, Mr. Holmes, do tell him that I know him to be innocent.”

“I will, Miss Turner.”

“I must go home now, for dad is very ill, and he misses me so if I leave him. Good-bye, and God help you in your undertaking.” She hurried from the room as impulsively as she had entered, and we heard the wheels of her carriage rattle off down the street.

“I am ashamed of you, Holmes,” said Lestrade with dignity after a few minutes’ silence. “Why should you raise up hopes which you are bound to disappoint? I am not over-tender of heart, but I call it cruel.”

“I think that I see my way to clearing James McCarthy,” said Holmes. “Have you an order to see him in prison?”

“Yes, but only for you and me.”

“Then I shall reconsider my resolution about going out. We have still time to take a train to Hereford and see him to-night?”

“Ample.”

“Then let us do so. Watson, I fear that you will find it very slow, but I shall only be away a couple of hours.”

I walked down to the station with them, and then wandered through the streets of the little town, finally returning to the hotel, where I lay upon the sofa and tried to interest myself in a yellow-backed novel. The puny plot of the story was so thin, however, when compared to the deep mystery through which we were groping, and I found my attention wander so continually from the fiction to the fact, that I at last flung it across the room and gave myself up entirely to a consideration of the events of the day. Supposing that this unhappy young man’s story were absolutely true, then what hellish thing, what absolutely unforeseen and extraordinary calamity could have occurred between the time when he parted from his father, and the moment when, drawn back by his screams, he rushed into the glade? It was something terrible and deadly. What could it be? Might not the nature of the injuries reveal something to my medical instincts? I rang the bell and called for the weekly county paper, which contained a verbatim account of the inquest. In the surgeon’s deposition it was stated that the posterior third of the left parietal bone and the left half of the occipital bone had been shattered by a heavy blow from a blunt weapon. I marked the spot upon my own head. Clearly such a blow must have been struck from behind. That was to some extent in favour of the accused, as when seen quarrelling he was face to face with his father. Still, it did not go for very much, for the older man might have turned his back before the blow fell. Still, it might be worth while to call Holmes’s attention to it. Then there was the peculiar dying reference to a rat. What could that mean? It could not be delirium. A man dying from a sudden blow does not commonly become delirious. No, it was more likely to be an attempt to explain how he met his fate. But what could it indicate? I cudgelled my brains to find some possible explanation. And then the incident of the gray cloth seen by young McCarthy. If that were true the murderer must have dropped some part of his dress, presumably his overcoat, in his flight, and must have had the hardihood to return and to carry it away at the instant when the son was kneeling with his back turned not a dozen paces off. What a tissue of mysteries and improbabilities the whole thing was! I did not wonder at Lestrade’s opinion, and yet I had so much faith in Sherlock Holmes’s insight that I could not lose hope as long as every fresh fact seemed to strengthen his conviction of young McCarthy’s innocence.

It was late before Sherlock Holmes returned. He came back alone, for Lestrade was staying in lodgings in the town.
