"She was in Barnstead on the night of the murder," replied Paul, sharply; "and by the evidence of that feather she must have been in the Winding Lane on the night of the murder."
"I can't see her reason."
"I can. She heard that Herne was engaged to Milly and came down to see her. She followed her to the Winding Lane, and, for all I know, shot her."
"Why should she shoot Milly?" cried Lester, rising.
"I don't know; I can't say. I must find out. Lester, not a word of this to anyone. You return to Barnstead with Iris, and I'll go up to London to-morrow."
"To see Catinka?"
"Yes, and Herne. What; you don't know? Herne has gone up to London also, about that feather. I am sure of it, though I have no proof. I'll call at Bloomsbury Square, and find out the truth about him and Catinka. Also, I'll know why she came to Barnstead, and what she was doing in the Winding Lane."
"But how can you get her to speak?"
"How? By means of the Rainbow Feather, of course!"
