In Cards on the Table (S10E02) Hercule Poirot states:

The question is, can Hercule Poirot possibly be wrong?

No one can always be right.

But I am.

Always I am right.

It is so invariable it startles me.

Was that right? Has there been any instance, where he made a mistake?

I have seen only a few episodes, and I cannot recall any such occurrence.

I presume you are asking about the TV series starring David Suchet, rather than the novels or any other TV or movie versions.

In The Mysterious Affair at Styles, (season 3, episode 1) Hastings recalls an earlier meeting with Poirot, where murder had occurred, and Hastings was Poirot's suspect for a time.

  • Thanks, you are right, as the assertion is from the TV series, the question is primarily targeted at it. Altough the novels' point of view would be interesting too!

  • "suspect" doesn't mean Poirot "claims he did it". There's usually several suspects in a case, and usually all but one of them turn out to be not guilty of the murder. Did Poirot state that Hastings did it, or did he merely suspect him?
