Lies and secrets are troublesome in real life, I guess, but in fiction they are well-nigh indispensable. Secret weddings, secret births, adultery, concealed crimes–all are the very stuff of fiction. Misunderstandings and mistakes can be funny, but lies and secrets, because they are intentional, are usually serious business.
The mystery writer Tana French is a master of lies and secrets. From her 2007 debut, In The Woods, French’ s Dublin detectives (a different detective narrates each book, so characters overlap but viewpoints change) have solved complex crimes, but they do much more than that. They uncover secrets kept by witnesses, family and friends of the victim and suspects, and they also reveal to us the lies they have told and the secrets they have kept even from themselves.
