Splinters is a high-ranking member of the Family and is an antagonist in Professor Layton and the Unwound Future. He is first seen in the Casino, like a lot of the other mobsters, during the shootout. Later on, he is seen in Cogg's flashback. He attacked Cogg with Lockjaw, and Bostro uses the Time Machine. Splinters was also one of the many goons in the Research Facility, later towards the end of the game.
Splinters gives no puzzles to Layton and Luke as they don't meet him in the game directly.
Splinters is a brutish, bloodthirsty man who works for Bostro. Surprisingly, his hobby is collecting old clocks, and he often makes secret visits to the clock shop. Though still only a young man of 28, he's already concerned by his receding hairline.
