The Hercule Poirot series is currently being re-run here and I don't think it is up to the usual standard of such programs - a few too many errors that really annoy me. One is the speech of the characters, in several instances they use idioms which seem out-of-character - an upper-crust person using a slang expression, for example. Now while upper crust folks have no doubt gone slumming from time to time and picked up the lingo, it's when it is used by an unlikely character.....say, an elderly lady......that it doesn't ring true.
