Once more I waited. She spoke--but it was not to reply: it was only to change the subject.
"The time is passing," was all she said. "We have not begun your letter to your mother yet."
It would have been cruel to contend with her any longer. Her voice warned me that she was suffering. The faint gleam of light through the parted curtains was fading fast. It was time, indeed, to write the letter. I could find other opportunities of speaking to her before I left the house.
"I am ready," I answered. "Let us begin."
The first sentence was easily dictated to my patient secretary. I informed my mother that my sprained wrist was nearly restored to use, and that nothing prevented my leaving Shetland when the lighthouse commissioner was ready to return. This was all that it was necessary to say on the subject of my health; the disaster of my re-opened wound having been, for obvious reasons, concealed from my mother's knowledge. Miss Dunross silently wrote the opening lines of the letter, and waited for the words that were to follow.
In my next sentence, I announced the date at which the vessel was to sail on the return voyage; and I mentioned the period at which my mother might expect to see me, weather permitting. Those words, also, Miss Dunross wrote--and waited again. I set myself to consider what I should say next. To my surprise and alarm, I found it impossible to fix my mind on the subject. My thoughts wandered away, in the strangest manner, from my letter to Mrs. Van Brandt. I was ashamed of myself; I was angry with myself--I resolved, no matter what I said, that I would positively finish the letter. No! try as I might, the utmost effort of my will availed me nothing. Mrs. Van Brandt's words at our last interview were murmuring in my ears--not a word of my own would come to me!
Miss Dunross laid down her pen, and slowly turned her head to look at me.
"Surely you have something more to add to your letter?" she said.
"Certainly," I answered. "I don't know what is the matter with me. The effort of dictating seems to be beyond my power this evening."
"Can I help you?" she asked.
I gladly accepted the suggestion. "There are many things," I said, "which my mother would be glad to hear, if I were not too stupid to think of them. I am sure I may trust your sympathy to think of them for me."
That rash answer offered Miss Dunross the opportunity of returning to the subject of Mrs. Van Brandt. She seized the opportunity with a woman's persistent resolution when she has her end in view, and is determined to reach it at all hazards.
