" We passed a very pleasant evening, though I made the slight mistake of taking Poirot to a crook play. There is one piece of advice I offer to all my readers. Never take a soldier to a military play, a sailor to a naval play, a Scotsman to a Scottish play, a detective to a thriller -- and an actor to any play whatsoever! The shower of destructive criticism in each case is somewhat devastating. "
― Agatha Christie , Dumb Witness (Hercule Poirot, #15)
