I have thoroughly enjoyed the Little Dorrit drama on BBC, but I still don't fully understand what the big secret was. So if someone could clarify I would be grateful. I think the problem was the secret was revealed by that French Murderer and I couldn't understand a word he was saying.
This is what I think the secret was. Old mum Clenham's husband was free and easy with dancers and used to get them pregnant. Amy was one of them that was given away to the dorrit family, but really she is a clenham. And Arthur was also an offspring of his dad's affairs, but his mum wasnt really his mum, but she just brought him up. Which made them half brother and sister. But this can't be right as they wouldn't have been able to get married at the end.
