Imagine you are at a pub quiz. It’s the literature round and the theme is literary firsts. What was the first novel in English? What was the first detective story? Readers of Slightly Foxed could probably hazard a guess at Robinson Crusoe and The Murders in the Rue Morgue. But what was the first ever piece of detective fiction written by a woman? It’s a question likely to leave most readers stumped. But just in case it ever comes up, the answer is The Leavenworth Case by Anna Katharine Green, published in 1878.
