Montsaye High: Slides of Montsaye murder:
The first time you visit Montsaye High (the very first level), after freeing the ghosts
and the intermission sequence with Hawksmoor and Anna in the attic, but before you
go there, go to one of the classrooms that appears to be a science-type room. On a
table near the window is a television and slide projector. Approach the projector and
an option for action appears. Press this button to see a mysterious shadowy figure.
Press it again to see another image. Keep doing this until you return to the original
slide.

View Ghosts:
After you have captured the medieval ghosts and captured the blue spook and the
revenant in the attic, there will be an intermission sequence. You will now be able to
view the ghosts you have captured through a viewing panel where Lazarus released
the ghosts, at any time throughout the game. Note: You can only view the ghosts
when you are at Montsaye High.
