A priceless ruby vanishes and a clerk is seized when a bloody thumbprint seals his guilt. Yet a cool-headed physician-lawyer suspects the mark itself is a trap. With microscopes, reagents, and pitiless logic, he dissects alibis and laboratory tricks, exposing how evidence can be manufactured—and how a single smudge could hang a man. A courtroom duel turns science into salvation.
