"They have their spies everywhere," she said doggedly.
"Who have?"
"The Secret Service people from other countries. Lord Wisbeach was telling me about it yesterday. He said that I ought to suspect everybody. He said that an attempt might be made on Willie's invention at any moment now."
"He was joking."
"He was not. I have never seen any one so serious. He said that I ought to regard every fresh person who came into the house as a possible criminal."
"Well, that guy's fresh enough," muttered Ogden from the settee.
Mrs. Pett started.
"Ogden! I had forgotten that you were there." She uttered a cry of horror, as the fact of his presence started a new train of thought. "Why, this man may have come to kidnap you! I never thought of that."
Ann felt it time to intervene. Mrs. Pett was hovering much too near the truth for comfort. "You mustn't imagine things, aunt Nesta. I believe it comes from writing the sort of stories you do. Surely, it is impossible for this man to be an impostor. How would he dare take such a risk? He must know that you could detect him at any moment by cabling over to Mrs. Crocker to ask if her step-son was really in America."
It was a bold stroke, for it suggested a plan of action which, if followed, would mean ruin for her schemes, but Ann could not refrain from chancing it. She wanted to know whether her aunt had any intention of asking Mrs. Crocker for information, or whether the feud was too bitter for her pride to allow her to communicate with her sister in any way. She breathed again as Mrs. Pett stiffened grimly in her chair.
