“Oh, very well. It does not matter. Who did you think was pursuing Mr. Hammersley?”
“Agents of Mr. Rizzio.”
“Why did you think that?”
“Because I heard part of what happened between Mr. Rizzio and Mr. Hammersley in the smoking-room at Lady Heathcote’s and I knew that Mr. Rizzio had threatened Mr. Hammersley.”
“Did you think the men who followed you in the other machine were German agents?”
Doris answered quickly.
“Oh, no. I was sure that they were men of Scotland Yard.”
“Are you sure now?”
“Oh, yes. Subsequent events have proved it to me conclusively.”
