We went directly above; and this time found the room we wished to visit, open. As the face of its natural occupant could be plainly seen from where we stood, we gratified our curiosity by a momentary contemplation of it. Like his brother, Alfred Gillespie was sitting at a table, but he was neither flushed with wine nor engaged in idle revery. On the contrary, he was very busy writing letters. But he was not satisfied with his work. He looked restless and disturbed, and, in the minute or two we stood there watching him, tore up the wretched scrawls he had just indited, with a groan indicative not only of impatience, but deep, almost heartrending anguish. On his pale brow and in his attenuated frame few signs remained of the once luxurious Alfred, and when, after a second attempt at expressing himself, he made a dash at the unfinished letter and, crumpling it to nothing in his hand, threw it into the fire, I turned to Sweetwater and whispered:

"Cut this misery short."

The young detective nodded, and with a clearing of his throat, meant, I am sure, as a warning, he advanced and entered the room, into which I rapidly followed him. Without pausing for any greeting from the astonished Alfred, he at once presented me in the following manner:

"Mr. Gillespie, will you allow me the honour of presenting Mr. Outhwaite, who has come to offer you his hearty congratulations?"

"Congratulations!" I don't know whether I was more moved by the sarcasm or the despair expressed in this repetition of the word, which must have fallen with strange effect on Alfred Gillespie's ear. "For what, may I ask?"

"For the speedy lifting of the cloud which has darkened this house; for the free and honourable return of your brother from his present place of detention, and the incarceration in his stead of the old man, Hewson, who has just confessed to the crime of having poisoned your father."

"Hewson! Old Hewson!" Alfred rose with a wild laugh that was not unlike a curse. "You are playing with me! You are——"

"No," I interposed, with a decision he could not but recognise. "Far from it, Mr. Gillespie. What the detective says is true. Hewson acknowledges the whole thing. He wanted a little home, knew that a legacy awaited him at your father's death, and wished to hasten his enjoyment of it. Your father recognised him as his poisoner when too late. He tried to communicate the fact to Miss Meredith in the five words: 'None of my sons. Hewson,' but his strength failed him, and he only succeeded in impressing on the paper the unfinished words: 'one of my sons he.' The detective will explain."

"Ah!" was his troubled response, as he sank back into the seat from which he had risen. Then as he met our eyes fixed sympathetically upon him, he dropped his head upon his arms, crying brokenly: "Don't look at me! Don't look at me! All this misery and shame! And it was Hewson! Oh, Hope! Hope!"

We left him. It was all we could do. As we stepped down together into the lower hall, Sweetwater remarked to me, with one of his rare smiles:
