The Red Thumb Mark

A bloody print upon gold seems to condemn a man beyond appeal—until Freeman’s scientific barrister-detective shows how laboratory method may test even the newest certainty. It is the origin of a series, and still one of its clearest statements: evidence is not the same as truth until it has been examined.
