Part 18

"Of what?"

"Well, the truth concerning the death of Miss Gabrielle Engledue."

"The death of Miss Gabrielle Engledue!" he cried. "I really don't understand you, Mr.--Mr. Garfield!"

At mention of the name I saw that he started, but almost imperceptibly. The man was certainly a most perfect actor, and his protestations of ignorance were, indeed, well-feigned.

"Then you actually deny all knowledge of the young lady!" I said.

"I know no lady of that name."

"But she is your niece."

"I have only one niece--Lady Shalford."

"And how old is she?"

He hesitated for a few moments. Then he answered.

"Oh! She must be about thirty-five. She married Shalford about ten years ago, and she lives at Wickenham Grange, near Malton, in Yorkshire."

"And you have no other niece?"

"None--I assure you. But why do you ask such a question? You puzzle me."

"Not more than you puzzle me, Mr. De Gex," I replied with pique. "It would be so much easier if you would be frank and open with me."

"My dear sir, you seem to me to have a bee in your bonnet about something or other. Tell me, now, what is it?"

"Simply that you know me very well, but you deny it. You never thought that I should make this unwelcome reappearance."

"Your appearance here as a mad-brained person is certainly unwelcome," he retorted. "You first tell me that you visited me at Stretton Street. Well, you may have been in the servants' quarters for all I know, and----"

"Please do not be insulting!" I cried angrily.

"I have no intention of offering you an insult, sir, but your attitude is so very extraordinary! You speak of a girl named Engledue--that was the name, I think--and allege that she is my niece. Why?"

"Because the young lady is dead--she died under most suspicious circumstances. And you know all about it!" I said bluntly.

"Oh! perhaps you will allege that I am a murderer next!" he laughed, as though enjoying the joke.

"It is no laughing matter!" I cried in fury.

"Why not? I find all your allegations most amusing," and across his dark handsome face there spread a good-humoured smile.

His was a face that I could never forget. At one moment its expression was kindly and full of bonhomie, the next it was hard and unrelenting--the face of an eccentric criminal.

"To me they are the reverse of amusing," I said. "I allege that on the night of Wednesday, November the seventh last, I was passing your house in Stretton Street, Park Lane, when your man, Horton, invited me inside, and--well, well--I need not describe what occurred there, for you recollect only too vividly--without a doubt. But what I demand to know is why you asked me in, and what happened to me after you gave me that money?"

"Money! I gave you money?" he cried. "Why, man alive, you're dreaming! You must be!"

"I'm not dreaming at all! It is a hard fact. Indeed, I still have the money--five thousand pounds in bank notes."

Oswald De Gex looked at me strangely. His sallow face coloured slightly, and his lips compressed. I had cornered him. A little further firmness, and he would no doubt admit that we had met at Stretton Street.
