From Affinity, by Sarah Waters, a dark and moody novel of psychological suspense set in the Victorian era:
I saw her looking at the pictures I have pinned at the side of my desk, and then at this book. I had closed the covers, but had my pen between the pages to keep the place. “What’s that?” she said. “What are you writing there?” She said it was unhealthy to sit at a journal so long; that it would throw me back upon my own dark thoughts and weary me.
Nowadays I suppose most people see journaling as therapeutic, rather than something unhealthy that throws them back upon their dark thoughts!
