"Then that dinner was a plant!" Mr. Cullen interrupted swiftly. "I knew it!"

I ignored the interruption.

"For the first time," I repeated; "and I find them both most delightful companions. As to how far our acquaintance may progress, that is entirely a matter for chance to decide. You have doubtless come here with very good motives, but I see no reason why I should accept your statements concerning Mr. Parker and his daughter. You understand? My suggestion is that you are mistaken. Until I have proved them to be other than they represent themselves to be," I added with infinite subtlety, "I shall continue to derive pleasure from their society."

Mr. Cullen rose at once to his feet.

"My warning has been given, sir," he said. "It only remains for me now to wish you good morning, and to assure you most regretfully that your name will be added to those whom Scotland Yard thinks it well to watch and that your movements from place to place will be noted."

"I trust that Scotland Yard will benefit," I replied politely, and showed him out.

At half past ten I rang up 3771A Gerrard. The telephone was answered almost immediately by a man, apparently a servant. I inquired for Mr. Parker and in a moment or two I heard his voice at the telephone.

"This is Joseph H. Parker speaking. Who are you?"

"I am Paul Walmsley. You told me I might ring up between ten and eleven."

"Sure!" was the prompt reply. "My dear fellow, I am delighted to hear from you. None the worse for our little adventure last night, I hope?"
