Pubblicato in italiano con il titolo Poirot non sbaglia. Anche a Poirot non piace andare dal dentista, ma ha tutte le intenzioni di provare che la sua morte non è un suicidio. Ma chi poteva volerlo morto?

Even a visit to the dentist turns into a murder investigation for Hercule Poirot. Indeed, right after his visit at the dentist, Poirot receives a call from Inspector Japp informing him that his dentist has been found dead, shot to the head. The police is sure that it is self-inflicted, but Poirot is not convinced. And, when one of his patients is found dead from a dose of anaesthetic, the police concludes that it is a case of accidental death-suicide. Hower, for the Belgian detective something else is afoot…

I think this is one of the most complex cases for Poirot that I’ve read so far. Full of twists and surprises, I didn’t see the truth coming. An incredible mystery that will keep you on the edge of your seat from the first (especially if you don’t like visits to the dentist) to the last page!
