After the water supply of three residential areas is poisoned, countless lives are lost.
While the authorities chase down terrorist leads, psychologist David Joseph suspects something even more sinister: a disturbed individual, driven to insanity by a world that ignored him. David must piece together the clues, but this case is more difficult than anything he's encountered before.
The stakes are high, and the next attack could happen anywhere. David and the law enforcement agencies race against time to track down the killer, but can they bring him to justice before he strikes again?
A gripping crime thriller, AN INSANE MIND is the fourth book in the David Joseph Mysteries series by Terence Newnes.
