“When do you expect your master back?” I asked at last.
“Oh, not for another six months or so.”
“Where is Mrs. De Gex?”
“Ah! That I can’t quite make out,” he replied. “It’s a bit of a mystery. One night she went away quite unexpectedly and, as a matter of fact, nobody knows where she is. Her husband doesn’t know – or pretends he doesn’t,” he said with a knowing grin.
“Then she has disappeared!” I exclaimed.
“That’s just it. And they were always such a devoted pair. Little Oswald was the only thing she lived for.”
“Lived!” I echoed. “Then do you think she’s dead?” I asked quickly.
“Dead! Why should we think so? If she were, we should surely have seen it in the papers?”
“But your master has very funny fits sometimes,” I said. “I’ve heard about his eccentric ways.”
“Of course he has. He’s overburdened with money – that’s what it is. Mr. Henderson looks after all his affairs. Mr. De Gex has no regard for money. Mr. Henderson attends to everything. Phew! I wish I were a millionaire! I find it hard enough nowadays to pay the butcher and baker and make both ends meet.”
“And so do I,” I said, laughing. “But, tell me, where is the young lady who used to live here – Mr. De Gex’s niece?”
“His niece! I don’t think he has a niece.”
“Miss Gabrielle Engledue.”
“Who’s she? I’ve never heard of her,” was the man’s reply.
I described her, but he shook his head.
“To my knowledge Mr. De Gex hasn’t got a niece,” he said.
“Were you here five weeks ago?” I inquired.
“Five weeks ago? No. I and my wife went away down to Swanage to see her sister. The master gave us a fortnight’s holiday. Why?”
“Oh – nothing,” I replied. “I merely inquired as I want to clear up a mystery – that’s all.”
“What mystery?”
“The mystery of Miss Engledue – your master’s niece,” I answered.
“But I’ve never heard of any niece,” he said.
“A young lady of about twenty-one with dark hair and eyes, and a beautiful complexion,” I said.
But the old servant’s mind was a blank.
“Of course, sir, many people come to visit Mr. De Gex. Horton would know them, but I don’t. When the master is in town the servants are here, and I’m down in Cornwall at the castle.”
“Then you are only here as caretaker when the family is away?”
“That’s it, sir,” he said. “But what is the mystery about this young lady? You said you knew Mr. De Gex, and yet you wanted to look over the house.”
“Yes,” I responded with a laugh. “I have my own object – to clear up the mystery of Mr. De Gex’s niece.”
“Well, as far as I know, he has no niece! But you could easily find out, I suppose!”
The man was evidently no fool.
“Of course I don’t know who comes here, or who stays here when the family is in town,” he went on. “I simply come up and look after the place with my wife.”
“Then you were away in Swanage during the first week of November?” I asked very seriously.
“Yes, we went down on the last day of October, and we were back here in the middle of November. My wife’s sister was very ill, and her husband didn’t expect her to live. So I remember the dates only too well.”
“Then the family were in town on the date I mention.”
He considered a moment.
“Oh! Of course they were. They must have been.”
I glanced again around the room, full of amazement and wonder.
The man’s failure to give me any details regarding the extremely attractive girl who had died upon his mistress’s bed held me gripped in uncertainty. The mystery was even more puzzling now that I had started to investigate.
As I stood in that room a thousand strange reflections flashed across my mind.
Why had I, a mere passer-by, been called in so suddenly to be taken into the intimacy of the millionaire’s household? Was it by mere accident that I had been invited in, or was it by careful design? I had lost five thousand pounds by foolish speculation, and yet I had regained it by being party to a criminal offence.
Again, who was the pretty, dark-haired girl who had first uttered those hysterical screams, and then, while fully dressed, had died upon Mrs. De Gex’s bed? Further, if the mysterious dead girl had been niece of the millionaire surely my friend the caretaker would have known her?
I confess that I now became more bewildered than ever.
That a girl named Gabrielle Engledue – whoever she might have been – had died, and that I had forged a certificate showing the cause of death were hard, solid facts. But the mystery of it all was complete.
That I had been the victim of some very carefully prepared and subtle plot was apparent, and it had become my own affair to investigate it and bring to justice those who were responsible for the poor girl’s death.
Time after time I questioned the caretaker regarding the existence of the millionaire’s niece, Miss Engledue, but it was plain to me that he had no knowledge of any such person.
“Was there not a death in this house – about five weeks ago?” I asked.
“Death?” he echoed. “Why, no, sir. You must be dreaming. If there had been a death while I was away, either my wife or I would certainly have heard about it.” And he looked suspiciously at me as though he believed I had taken leave of my senses.
An hour later I was back at Rivermead Mansions, where Harry, for whom I had left a note, was awaiting me.
As we sat together before a cheerful fire I told him of my lapse into unconsciousness, of my loss of memory, but I did not explain all that had happened, for, as a matter of fact, I had no desire that anyone should know of my guilt in posing as a medical man and thus becoming implicated in the mysterious death of Gabrielle Engledue.
My friend sat and heard me, smoking his pipe in silence.
