Jack Renauld

Jack Renauld - Paul Renauld's son, born in South America (presumably anywhere near Santiago, Chile), and raised both there and in France. He was mistakenly suspected of murder by stubborn inspector Giraud, due to an argument between him and his father. He was formerly in love with Marthe, now in love with Bella. He was sent to Chile by Paul, but Jack refused and stayed in France, thus he lacked an alibi.

In Les Petits Meurtres d'Agatha Christie, he was renamed Miguel. Here his portrayal isn't very faithful to the original character apart from some details. For more information visit this article.
