Later in the day I was told that Mrs. Rymer had called, and wished to "pay her respects."

I refused to see her. Whatever claim she might have otherwise had on my consideration had been forfeited by the infamy of her conduct, when she intercepted my letter to Susan. Her sense of injury on receiving my message was expressed in writing, and was sent to me the same evening.

The last sentence in her letter was characteristic of the woman.

"However your pride may despise me," she wrote, "I am indebted to you for the rise in life that I have always desired. You may refuse to see me--but you can't prevent my being the mother-in-law of a gentleman."

Soon afterward, I received a visit which I had hardly ventured to expect. Busy as he was in London, my doctor came to see me. He was not in his usual good spirits.

"I hope you don't bring me any bad news?" I said.

"You shall judge for yourself," he replied. "I come from Mr. Rothsay, to say for him what he is not able to say for himself."

"Where is he?"

"He has left England."

"For any purpose that you know of?"

"Yes. He has sailed to join the expedition of rescue--I ought rather to call it the forlorn hope--which is to search for the lost explorers in Central Australia."

In other words, he had gone to seek death in the fatal footsteps of Burke and Wills. I could not trust myself to speak.

The doctor saw that there was a reason for my silence, and that he would do well not to notice it. He changed the subject.

"May I ask," he said, "if you have heard from the servants left in charge at your house in London?"

"Has anything happened?"

"Something has happened which they are evidently afraid to tell you, knowing the high opinion which you have of Mrs. Mozeen. She has suddenly quitted your service, and has gone, n.o.body knows where. I have taken charge of a letter which she left for you."

He handed me the letter. As soon as I had recovered myself, I looked at it.

There was this inscription on the address: "For my good master, to wait until he returns home." The few lines in the letter itself ran thus:

"Distressing circ.u.mstances oblige me to leave you, sir, and do not permit me to enter into particulars. In asking your pardon, I offer my sincere thanks for your kindness, and my fervent prayers for your welfare."

That was all. The date had a special interest for me. Mrs. Mozeen had written on the day when she must have received my letter--the letter which has already appeared in these pages.

"Is there really nothing known of the poor woman's motives?" I asked.

"There are two explanations suggested," the doctor informed me. "One of them, which is offered by your female servants, seems to me absurd. They declare that Mrs. Mozeen, at her mature age, was in love with the young man who is your footman! It is even a.s.serted that she tried to recommend herself to him, by speaking of the money which she expected to bring to the man who would make her his wife. The footman's reply, informing her that he was already engaged to be married, is alleged to be the cause which has driven her from your house."

I begged that the doctor would not trouble himself to repeat more of what my women servants had said.

"If the other explanation," I added, "is equally unworthy of notice--"

"The other explanation," the doctor interposed, "comes from Mr. Rothsay, and is of a very serious kind."

Rothsay's opinion demanded my respect.

"What view does he take?" I inquired.

"A view that startles me," the doctor said. "You remember my telling you of the interest he took in your symptoms, and in the remedies I had employed? Well! Mr. Rothsay accounts for the incomprehensible recovery of your health by a.s.serting that poison--probably administered in small quant.i.ties, and intermitted at intervals in fear of discovery--has been mixed with your medicine; and he a.s.serts that the guilty person is Mrs.

Mozeen."

It was impossible that I could openly express the indignation that I felt on hearing this. My position toward Rothsay forced me to restrain myself.

"May I ask," the doctor continued, "if Mrs. Mozeen was aware that she had a legacy to expect at your death?"

"Certainly."

"Has she a brother who is one of the dispensers employed by your chemists?"

"Yes."

"Did she know that I doubted if my prescriptions had been properly prepared, and that I intended to make inquiries?"

"I wrote to her myself on the subject."

"Do you think her brother told her that I was referred to _him_, when I went to the chemists?"

"I have no means of knowing what her brother did."

"Can you at least tell me when she received your letter?"

"She must have received it on the day when she left my house."

The doctor rose with a grave face.

"These are rather extraordinary coincidences," he remarked.

I merely replied, "Mrs. Mozeen is as incapable of poisoning as I am."

The doctor wished me good-morning.

I repeat here my conviction of my housekeeper's innocence. I protest against the cruelty which accuses her. And, whatever may have been her motive in suddenly leaving my service, I declare that she still possesses my sympathy and esteem, and I invite her to return to me if she ever sees these lines.

I have only to add, by way of postscript, that we have heard of the safe return of the expedition of rescue. Time, as my wife and I both hope, may yet convince Rothsay that he will not be wrong in counting on Susan's love--the love of a sister.

In the meanwhile we possess a memorial of our absent friend. We have bought his picture.

MR. CAPTAIN AND THE NYMPH.
