The Valley Of Fear Act 2 Scene 8

McMurdo plans to trap Birdy Edwards and has gathered the importamt men of the lodege to do so. What nobody else understands is that McMurdo doesn't have to "trap" Birdy Edwards..... he is Birdy Edwards.

“I’d like to say a word to you before we separate,” said the man who had trapped them. “I guess we may not meet again until you see me on the stand in the courthouse. I’ll give you something to think over between now and then. You know me now for what I am. At last I can put my cards on the table. I am Birdy Edwards of Pinkerton’s. I was chosen to break up your gang. I had a hard and dangerous game to play. Not a soul, not one soul, not my nearest and dearest, knew that I was playing it. Only Captain Marvin here and my employers knew that. But it’s over to-night, thank God, and I am the winner!”
