Segal (Grafton in the British version) is a character appearing in Professor Layton and the Unwound Future. He can usually be found at the Black Market, right before the entrance of Chinatown. He is married to Margaret, the manager of the Hotel Duke, and may be Becky's grandfather as well. However, he has lately been having some trouble with his marriage and Margaret is also displeased in him, but at the credits he gives her a rose and their blooming relationship starts again.
Segal is found in the Black Market and gives Layton and Luke a puzzle or two during their adventures in Future London. The puzzles he gives are "Wheat Stash" and "The Two Necklaces". Another puzzle he gives is "Three Blocks".
