Miss Peregrine's Home for Peculiar Children 290-297

Enoch, Bronwyn, Emma, and Jacob all go to the market where they sell fish in freezers. Martin's body is in one of the freezers and Enoch brought a lot of sheep hearts to put into Martin's body to bring him back to life. Enoch is a dead-riser; he can bring bodies back to life for periods of time. So, when Martin wakes up, Jacob talks to Martin about the night of the murder. And when Jacob asks who did it, Martin looks to the doorway and says, "Him!" Who is it and what are they going to do?
