"Yes. Then she went to Miss Elliott's. That was on a Monday. Monday night, you will remember, Lawrence killed Fullerton, and the next day he was arrested. That stopped their plans, whatever they were. She has kept her room at Miss Elliott's, and I took this house, which happened to be vacant, so that I could keep a close watch on her. She has never gone out. Dr. Barry has been to see her, as you know. I have had Phillips get a daily report from Barry, under color of wiring to me.
"Then you came along, Mr. Lyon. I had seen and heard enough to know that you were a friend of Lawrence's, so I took you in, because I wanted to know everything about him that I could. And I knew that for some reason you were watching Grace. Phillips had tracked you there several times, and he followed you into the florist's shop and got possession of Grace's order for unlimited flowers to be sent to Lawrence. Her flowers for him! I wonder I have kept my senses. But I could do nothing but wait until Lawrence was released,--as Grace was waiting over there for his release! You needn't pretend to be surprised,--you know yourself the connection between them,--that's why you have been keeping a watch on her,--I saw that from the room you selected,--"
"You are quite right as to that, though I think you are quite wrong as to other things."
"What other things?"
"About Lawrence. He isn't that sort of a man. If anyone had a hold upon Mrs. Broughton, it would seem to have been Fullerton."
"Fullerton!"
"You have been very frank, Mr. Broughton, and it is only fair that I should be equally frank. We have been very anxious to have an interview with Mrs. Broughton as soon as her health would permit, Howell and I, because we have reason to believe that she may be able to throw some light upon the Fullerton murder. She may be wanted as a witness."
"You are mad,--utterly mad," gasped Broughton. "What could she possibly know about that?"
"She was with Fullerton when he left the Wellington at eight o'clock."
"I don't believe it!"
