After the shocking acquittal of two gang leaders who murdered police officers, America turns to a radical solution: Polygraph, a revolutionary justice system powered by the truth serum Veritas. Trials are replaced by interrogation chairs. Lies are stripped away in real time. Justice is instant.

For Detectives Hayes and Croft, the system delivers results beyond imagination, until the cracks appear. A mysterious new drug, Obscuron, surfaces on the streets. Engineered to disrupt Veritas, it leaves victims in comas and threatens to destroy the credibility of the entire Polygraph program. When a respected federal judge collapses in the chair, public trust wavers, political pressure mounts, and the race to uncover the source of Obscuron becomes a fight for survival.

As the line between law and conspiracy blurs, Hayes and Croft are drawn into a web of hidden payoffs, dangerous alliances, and scientific corruption. The deeper they dig, the more they realise, the truth may no longer be enough.

Polygraph is a tense, high-stakes thriller about power, trust, and the dangerous lines crossed in the name of justice. Perfect for readers of Michael Connelly, David Baldacci, and fans of fast-paced, morally complex crime fiction.
