Whispering Wires

A hard-boiled private detective is drawn into a tense mystery after a wealthy industrialist receives an anonymous telephone threat; the investigator mobilizes surveillance, traces whispering voices through early telephone networks, and examines servants, rivals, and past grudges. The narrative follows methodical searches, wire-tracing, and interviews that expose tangled motives among high society and criminal elements, while technology and detection techniques play a central role. Tension builds through a series of discoveries and reversals that culminate in the identification of the culprit and the resolution of the threatened plot.
