The Black Box by E. Phillips Oppenheim audiobook.

Genre: mystery

Sanford Quest is not a policeman, and he is not a magician - yet New York's most baffling crimes have a way of landing on his desk. Celebrated as the world's greatest criminologist, Quest relies on a cool, scientific mind, experimental gadgets, and a gift for reading human weakness to unravel cases everyone else has abandoned. When a strange chain of violence begins with an uncanny exhibit and a murder that refuses to make sense, Quest finds himself pulled into an expanding web of stolen valuables, eerie evidence that seems to move by itself, and taunting messages delivered in a small black box. As suspicion spreads and the authorities grow impatient, Quest must prove what is real, what is staged, and who is using fear as a weapon. Aided by his capable assistant Laura and a circle of uneasy allies, he follows the trail from city streets to foreign ports and harsh, remote landscapes, where each new clue raises the stakes and tightens the trap around him. Fast, episodic, and steeped in early 20th-century intrigue, this adventure blends classic detective work with sensational twists and scientific thrills.
