The Mill Mystery by Anna Katharine Green

Letters, my Lord. HAMLET.

My illness, though severe, was not of long continuance. In a week I was able to be about my room; and in a fortnight I was allowed to read the letters that had come to me. There were two, either of them calculated to awaken dangerous emotions; and, taken together, making a draft on my powers which my newly gained health found it hard to sustain. The one was signed Rhoda Colwell, and the other Dwight Pollard. I read Rhoda Colwell's first.
