Holmes rose and sat down at the table with his pen in his hand and a bundle of paper before him. "Just tell us the truth," he said. "I shall jot down the facts. You will sign it, and Watson here can witness it. Then I could produce your confession at the last extremity to save young McCarthy. I promise you that I shall not use it unless it is absolutely needed."
"It's as well," said the old man; "it's a question whether I shall live to the Assizes, so it matters little to me, but I should wish to spare Alice the shock. And now I will make the thing clear to you; it has been a long time in the acting, but will not take me long to tell.
"You didn't know this dead man, McCarthy. He was a devil incarnate. I tell you that. God keep you out of the clutches of such a man as he. His grip has been upon me these twenty years, and he has blasted my life. I'll tell you first how I came to be in his power.
"It was in the early '60's at the diggings. I was a young chap then, hot-blooded and reckless, ready to turn my hand at anything; I got among bad companions, took to drink, had no luck with my claim, took to the bush, and in a word became what you would call over here a highway robber. There were six of us, and we had a wild, free life of it, sticking up a station from time to time, or stopping the wagons on the road to the diggings.
Black Jack of Ballarat was the name I went under, and our party is still remembered in the colony as the Ballarat Gang.
"One day a gold convoy came down from Ballarat to Melbourne, and we lay in wait for it and attacked it. There were six troopers and six of us, so it was a close thing, but we emptied four of their saddles at the first volley. Three of our boys were killed, however, before we got the swag. I put my pistol to the head of the wagon-driver, who was this very man McCarthy. I wish to the Lord that I had shot him then, but I spared him, though I saw his wicked little eyes fixed on my face, as though to remember every feature. We got away with the gold, became wealthy men, and made our way over to England without being suspected. There I parted from my old pals and determined to settle down to a quiet and respectable life. I bought this estate, which chanced to be in the market, and I set myself to do a little good with my money, to make up for the way in which I had earned it. I married, too, and though my wife died young she left me my dear little Alice.
