The sound of screaming fills the air. Cal's identity has been stripped from him, and he's been locked up in an asylum where danger lurks on both sides of the bars. He has no idea who's put him there, but the doctors are convinced Cal - Ben Galloway - is delusional, and they have no intention of setting him free.

Cal can't reach his great-uncle Bartholomew, or solve the Dangerous Mystery of the Ormonds, when he's wearing a straightjacket... No one believes a word he says - not even the truth can save him now. The clock is ticking. Any second could be his last.
