A novel by J.F. Penn

Delirium

The line between sanity and madness is thinner than you think…

A psychiatrist descended from the family that ran Bedlam for three generations is found drowned in a Tranquilizer chair at the Imperial War Museum, the asylum's original site.

Each new murder restages one of Bedlam's historical treatments, and every victim is complicit in a modern abuse of the vulnerable.

As Jamie Brooke hunts an avenger who might be the sanest person in the case, Blake Daniel is pulled into his own past, and into the hands of an agency that experiments on people like him.

The manacles of Bedlam never came off. They just moved inside.
