The Ear in the Wall

A string of connected crimes begins with the unexplained disappearance of a young woman, prompting a district attorney and scientific investigators to pursue leads. Their inquiries expose a criminal network that manipulates courts, elections, and vice, involving shyster lawyers, gang leaders, and undercover operatives. Investigations hinge on clever forensic touches and odd clues — a safe robbery, a typewriter link, photographic measurements, and a mysterious chemical reaction — that produce escapes, confessions, and courtroom drama. Interleaved episodes explore scandal, blackmail, social entanglements, and a final unraveling that resolves many threads while revealing the reach of the corrupt organization.
