Blackstone and the Balloon of Death (Severn House Large Print)

Five hundred people saw the murder but no one knows who did it! - The entire audience at the George Theatre saw Charlotte Devaraux stab William Kirkpatrick with a fake dagger. But how did the murderer manage to exchange the fake dagger for a real one? What was smeared on the blade? Blackstone follows the trail through the depths of the Victorian freak show and a lunatic asylum. And though he does not know it, another murder is already being planned.
