After Mare (Kate Winslet) is forced to take a back seat on the investigation, Colin (Evan Peters) grills a local priest for more information on the nebulous circumstances that prompted his transfer to the local parish in the new episode “Poor Sisyphus.” Elsewhere, Dawn (guest star Enid Graham) gets a mysterious phone call that rekindles her hope that Katie is still alive. Julianne Nicholson, Jean Smart and James McArdle also star.
