'This play we're doing, it's not true, is it? I mean, there never was a Sweeney Todd who killed people?'

Jackus never wanted to be in the school play, but he didn't have much choice.

Ghostly footprints. Unexplained whispering. The touch of a cold hand in the shadows . . .

What has been woken by the play's dark words? Can Jackus stop it, or are the actors doomed to play out the tragedy to the bitter end?
