Now, it seems like you can’t look through a magnifying glass without seeing a dead body that’s turned up under suspicious circumstances, either in cinemas (the recent remakes of Murder on the Orient Express and Death on the Nile ) or on television ( Only Murders in the Building, Poker Face ). After decades of being woefully out of fashion, the classic whodunnit has returned to cultural prominence, thanks in large part to the leftfield success of 2019’s Knives Out and its even bigger follow-up, Glass Onion. It’s safe to say that the murder-mystery is back.
