"'You see it all now, don't you?' said Mr. Carter; 'that's why the clothes were stripped off the body, and hidden at the bottom of the stream, where the water seemed deepest; that's why the watch and chain changed hands; that's why the man who came back to this house after the murder was slow to select the key of the desk. You understand now why it was so difficult for Margaret Wilmot to obtain access to the man at Maudesley Abbey; and why, when she had once seen that man, she tried to shield him from inquiry and pursuit. When she told you that Henry Dunbar was innocent of her father's murder, she only told you the truth. The man who was murdered was Henry Dunbar; the man who murdered him was——'

"I could hear no more. The blood surged up to my head, and I staggered back and dropped into a chair.

"When I came to myself, I found the detective splashing cold water in my face. When I came to myself, and was able to think steadily of what had happened, I had but one feeling in my mind; and that was pity, unutterable pity, for the woman I loved.

"Mr. Carter carried the bundle of clothes to his own room, and returned by-and-by, bringing his portmanteau with him. He put the portmanteau in a corner near the fireplace.

"'I've locked the clothes safely in that,' he said; 'and I don't mean to let it out of my sight till it's lodged in very safe hands. That mark upon Henry Dunbar's shirt will hang his murderer.'

"'There may have been some mistake,' I said; 'the clothes marked with the name of Henry Dunbar may not have really belonged to Henry Dunbar. He may have given those clothes to his old valet.'

"'That's not likely, sir; for the old valet only met him at Southampton two or three hours before the murder was committed. No; I can see it all now. It's the strangest case that ever came to my knowledge, but it's simple enough when you've got the right clue to it. There was no probable motive which could induce Henry Dunbar, the very pink of respectability, and sole owner of a million of money, to run the risk of the gallows; there were very strong reasons why Joseph Wilmot, a vagabond and a returned criminal, should murder his late master, if by so doing he could take the dead man's place, and slip from the position of an outcast and a penniless reprobate into that of chief partner in the house of Dunbar and Company. It was a bold game to hazard, and it must have been a fearfully perilous and difficult game to play, and the man has played it well, to have escaped suspicion so long. His daughter's conscientious scruples have betrayed him.'

"Yes, Mr. Carter spoke the truth. Margaret's refusal to fulfil her engagement had set in motion the machinery by means of which the secret of this foul murder had been discovered.

"I thought of the strange revelation, still so new to me, until my brain grew dazed. How had it been done? How had it been managed? The man whom I had seen and spoken with was not Henry Dunbar, then, but Joseph Wilmot, the murderer of his master—the treacherous and deliberate assassin of the man he had gone to meet and welcome after his five-and-thirty years' absence from England!
