Ep 6. The Chocolate Box

Hercule Poirot is back with another intriguing case in season 5 episode 6, titled "The Chocolate Box". The episode begins with Poirot receiving a gift of a chocolate box from an old friend, Monsieur Bonneau. However, the chocolates inside are not the real focus of the episode, as the chocolate box serves as a clue to a decades-old crime.

As Poirot reminisces about his time in Belgium, he recalls a case he worked on 30 years ago. At that time, a young couple was found dead in a park, and Poirot was tasked with solving the crime. However, he was unable to find the culprit and the case had remained unsolved for all these years.

When a man named John Wilson approaches Poirot with new information about the old case, the detective comes out of retirement to investigate further. Wilson, it turns out, was a witness to the crime all those years ago - but was unable to come forward until now, for fear of being implicated himself. With Wilson's account of what happened, Poirot sets out to solve the murder once and for all.

The investigation takes Poirot to Brussels, where he meets with Monsieur Renauld - the victim in the original case, and the father of the young woman who was murdered. Renauld, who had since moved to England, seems to be hiding something. As Poirot delves deeper into the case, it becomes clear that the murder was not the simple crime of passion it was originally thought to be.

As Poirot follows the trail of clues, he encounters a web of deceit and betrayal - not just from the murderer, but from some unexpected sources. The Chocolate Box is a classic Poirot mystery, filled with unexpected twists and turns, and a resolution that will keep viewers on the edge of their seats until the very end.
