Walls of Silence took a lot of research. This novel stood on the shoulders of material I had gathered on shell-shock for a previous writing project. I added folders on the emergence of psychoanalysis, asylums in the 1920s, and the treatment & rehabilitation of those society considered mad. But total immersion in the grim subject of damaged minds was relieved by reading about subjects such as beekeeping, roses, herbal remedies, Gypsy lore, and village grocers’ shops. The topics I’ll be touching on here are equally eclectic.
