“As a human being, losing your real family is always painful,” he said.
“But my saddest day as an actor was filming Poirot’s death.
“I miss him in my life because he was my life for 25 years and I’ve lost my best friend.”

When asked what he thought the essence of Hercule Poirot was after all these years, Suchet explained: “He comes across as very self-sufficient, but Agatha Christie has him mention on several occasions that the greatest gift from God to human beings is a husband-and-wife relationship.
“I’d try to bring that out more as I aged with Poirot – that he would’ve loved to have had a companion.”
But he added cheekily: “However, no one person could have put up with him. He would be impossible to live with! He’s an egotistical perfectionist.”
Before lockdown, he took Poirot on tour in Australia and New Zealand with his one-man show Poirot and Me: A Retrospective, but he has hopes to revive it in the UK.
Wanting to showcase the show, which is an even split between the actor’s life story and his time as the detective, in the West End and then with a national tour, Suchet revealed it might “try to get people back into the theatre”, after what has been a dismal year for the performing arts sector.
And the ITV series, which ran for a total of 70 episodes between 1989 to 2013, has been enjoying a bit of a lockdown revival since it was added to ITV Hub, to which the actor admitted has done wonders for his popularity.
“My fan mail has increased three-fold with people who have watched the whole box set twice!” he told Radio Times.

Despite being his “best friend”, Suchet confessed he had never watched the show until he walked in on his wife rewatching the box sets.
“I don’t watch him – actually, that’s not true. My wife does,” he smiled.
“I walked into the room the other day and he was on and I sat next to her and watched him. I’m here to say that I actually quite enjoyed it!”
