Tracked by Wireless

In Short

Written in 1922, Tracked by Wireless follows Geoffrey Falconer, a brilliant young radio engineer whose newly invented amplifier allows him to hear secret high-frequency transmissions across Europe. When his friend Enrico Rossi mysteriously vanishes and a string of international plots unfolds, Geoffrey follows a trail of encrypted signals, stolen inventions, and hidden identities from London and Paris to Transylvania, Copenhagen, and Madrid. Combining early electronic espionage with classic high-society intrigue, William Le Queux crafts a fast-paced thriller that captures the dawn of global telecommunications and the shadows that moved behind its airwaves.

The Story

Geoffrey Falconer, an ambitious radio engineer working out of Chelmsford, perfects a supersensitive microphone amplifier that promises to bring him both fortune and professional acclaim. His technical triumph is quickly overshadowed, however, by a series of baffling events. First, a mysterious figure named George Glover integrates himself into London society and wins the favor of Mrs. Beverley, the mother of Geoffrey’s beloved Sylvia. Geoffrey’s suspicions are aroused when he intercepts strange wireless signals linked to Glover’s movements. Soon after, Geoffrey’s friend Enrico Rossi vanishes after sending a bogus, low-power telephonic message that purports to originate from mid-Atlantic.

Determined to untangle the mystery, Geoffrey collaborates with fellow engineers and informs the police. As he travels across Europe for the Marconi Company to set up experimental stations and consult with foreign officials, he repeatedly crosses paths with shadowy figures, false names, and secretive conspirators. In London, his friend Hugh Carew confesses to shooting an unscrupulous extortionist, Edward Everard, to protect a woman named Gabrielle and prevent Geoffrey’s wireless designs from being sold abroad. Meanwhile, in Denmark, Geoffrey uses a custom-built receiver in his Copenhagen hotel room to pinpoint an illicit Soviet radio station operating from the central square.

The intrigue deepens as Geoffrey travels to Hungary to test equipment for the Baron de Pelzel at the Schloss Nyék, where he succeeds in establishing long-range voice communications with Roumania under the watchful eyes of enigmatic guests. Throughout his travels, Geoffrey relies on wireless direction-finding, telegraphic cables, and his own sharp intuition to trace hidden connections between seemingly isolated crimes, including a fraudulent plot surrounding an Egyptian mine.

The sprawling trail culminates in Spain. While visiting a villa near Madrid with Sylvia and their hosts, Geoffrey learns of the Crow's Cliff, a historic precipice where victims of dark secrets have historically met their end. There, he confronts Martin, a sinister operative disguised as a trustworthy butler who has been orchestrating covert actions and attempting to silence accusers. Martin attacks Geoffrey near the cliff’s edge, but Geoffrey uses his training in self-defense to turn the assault against his attacker. Martin plunges over the precipice to his death. With the international network exposed, Geoffrey earns substantial royalties for his inventions, secures Mrs. Beverley’s consent, and marries Sylvia at St. Martin’s-in-the-Fields surrounded by his engineering colleagues.

How It Unfolds

Signals in the ether Geoffrey tests his new supersensitive amplifier at Chelmsford and intercepts anomalous wireless signals. He grows suspicious of George Glover, a wealthy foreign newcomer who has charmed Sylvia’s mother and appears tied to the encrypted airwaves.

The missing engineer Enrico Rossi vanishes after a rogue wireless transmission misleads listeners about his location. Geoffrey examines hotel registers, consults Marconi colleagues, and alerts the London police to the broadcast’s true low-power origin.

Secrets and confessions In a private club room, Hugh Carew admits to shooting the thief Edward Everard. Carew reveals he fired the shot to protect his lover Gabrielle and stop Everard from stealing Geoffrey's wireless patents for foreign buyers.

Tracking the hidden station Armed with a specialized receiving apparatus, Geoffrey settles into a Copenhagen hotel overlooking the square. Working with direction-finding coordinates, he successfully isolates the exact location of a covert Soviet transmitter.

Tests in Transylvania Geoffrey travels to Schloss Nyék to establish long-range telephonic links for Czecho-Slovak interests. He achieves crisp voice modulation across the mountains, despite the unsettling behavior of his hosts and their departing guests.

Reckoning at Crow's Cliff While investigating a series of covert maneuvers in Spain, Geoffrey is ambushed on a high cliff by the operative Martin. Geoffrey counters the sudden assault, sending the villain over the edge, before returning home to marry Sylvia.

The People

• Geoffrey Falconer is a dedicated radio engineer and inventor. He seeks to advance the science of wireless communication and protect his proprietary work, facing lethal conspiracies along the way, and ultimately achieves professional success and marriage.
• Sylvia Beverley is Geoffrey’s charming, high-society fiancée. She wants to support Geoffrey's career while navigating London's social calendar, initial skepticism regarding his suspicions, and eventual dangerous encounters abroad.
• George Glover is an ostentatiously wealthy man claiming oil interests in Baku. He seeks access to London's elite and Mrs. Beverley’s inner circle, using his charm to hide his connection to covert wireless transmissions.
• Hugh Carew is Geoffrey’s troubled friend. Driven by a desperate need to save his lover Gabrielle from blackmail, he takes extreme measures that alter his future and send him fleeing toward South Africa.
• Martin is a deceptive agent posing as a reliable butler. He seeks to orchestrate clandestine plots without detection, but his violent confrontation with Geoffrey leads directly to his fatal undoing.

In Its Own Voice

“We wireless men are never optimists, you know. We always look for failure first. Success surprises us, and bucks us up.”

Geoffrey reflects on his working mindset while discussing his new amplifier with Sylvia prior to his departure for Hungary.

“On that starlit night the ether was alive with messages by ‘spark’ and continuous-wave being sent across the seven seas.”

The narrator captures the ambient buzz of early shortwave radio as Geoffrey sits with headphones on in a Copenhagen hotel room.

“The two men fought for life, there upon the very brink of the grave!”

The narrative reaches its peak of physical conflict during the desperate struggle on the heights of Crow's Cliff outside Madrid.

What It's Really About

Beneath its international chase plot, Tracked by Wireless explores the transforming power of new technology on human conflict. The story presents the ether not merely as a tool for commercial shipping or military communication, but as an invisible, borderless arena where criminals and detectives wage an unceasing war of signals. Le Queux emphasizes how modern inventions render distance irrelevant, allowing a solitary operator at a workbench in Chelmsford to expose conspiracies hatched in continental capitals. The narrative pits disciplined scientific observation against lawlessness, arguing that technical mastery, methodical evidence-gathering, and cool rationalism will inevitably decipher the hidden codes of the modern world.

Why Read It Today

Tracked by Wireless offers readers a fascinating look at early twentieth-century techno-fiction written right at the dawn of public broadcasting. As a member of the Institute of Radio Engineers, Le Queux infuses his narrative with authentic period terminology—vacuum tubes, direction-finding aerials, call-signals, and spark transmissions—that gives the adventure a distinctive historical flavor. It feels like stepping into a vintage world of Orient Express journeys, grand hotels, quiet London clubs, and bulky experimental apparatus held together by copper wire and battery power.

Readers who enjoy light historical mysteries will appreciate the story's unpretentious pace and clean focus on action. While the book exhibits the melodramatic turns, abrupt character introductions, and straightforward prose typical of 1920s popular serials, these features add to its period charm. It stands as an entertaining artifact of an era when radio was the cutting edge of global connectivity, ideal for anyone interested in the roots of the modern electronic thriller.
