Silent Hill Homecoming: Shepherd's Glen - Shepherd House (again)

Go to the kitchen. Destroy the boarded entrance and take the First Aid Kit.

Go back to the backyard and enter the basement. Cut through the foil and enter the secret room. Take the Bluesteel Shotgun from the cabinet and the Attic Key from the table.

Go upstairs to the second floor and open the door at the end of the corridor using the Attic Key. Go to the attic.

Attic

There is a Photo #10 behind the curtain, but the most important thing is a wardrobe that needs to be moved to uncover a secret passage. Go the secret room and solve the jigsaw puzzle (look at the pictures below). After that take the Silent Hill Map, read the letter and go downstairs to speak with Alex' mother.
