Erin Kelly returns to The Richard And Judy Book Club with her latest novel We Know You Know, a thriller set in and around a converted Victorian psychiatric hospital in Suffolk. Our heroine Marianne is a history of art lecturer, but the building itself is the true central character. Erin reveals what she learnt about the history of psychiatric medicine while doing research for this novel – her first foray into historical fiction – as well as how a friend’s Tinder date inspired the story.
