Carl is a café customer who makes his first appearance at level 16. He is an antiquarian and the person Margaret sells the player's stored items to. He is Margaret's husband and partner in crime. They got married 13 times but used each wedding day as a cover to rob a priceless item from a museum (except for the first one as Margaret explains that the robbery failed). They have been married for at least 50 years.
Carl practices savate boxing and seems to be quite good at it as he was able to take down four men on his own.
- Carl is Margaret's husband. (level 13)
Like Margaret, Carl can buy items the player has in their storehouse. However, he offers to buy 3 pieces a day instead of just one, and for better prices.
