History In 1933, the Hollywood icon known as "The Most Beautiful Woman in the World" sat trapped in a Nazi-aligned arms dealer’s castle. She used the dinner table as an unauthorized SCIF, mapping the fatal flaws of Axis torpedoes before escaping on a bicycle to invent modern Wi-Fi and Bluetooth.

History often segregates glamour from genius, treating beauty and intellect as mutually exclusive traits. But during the dark interwar period of the 1930s, one of the most sophisticated deep-cover intelligence harvests in history was executed by a nineteen-year-old Austrian actress named Hedwig Kiesler later known to the world as Hedy Lamarr.

Here is the declassified forensic breakdown of how Hollywood's biggest star engineered the foundational technology of the modern wireless world:

  • The Gilded Blacksite: In August 1933, nineteen-year-old Hedy was married off to Friedrich Mandl, a ruthless Austrian billionaire and the third-largest arms dealer on the planet. Mandl’s factories were illegally churning out millions of rounds of munitions for Benito Mussolini’s fascist regime and Adolf Hitler’s rearming Third Reich. Mandl trapped Hedy inside Schloss Schwarzenau, surrounding her with armed sentries and internal informants to strip away her autonomy.
  • The Unauthorized SCIF: Mandl routinely hosted high-level operational summits inside his dining rooms, welcoming senior Wehrmacht officers, Italian commanders, and Axis engineers. Blinded by systemic misogyny, these men assumed Hedy was a mere biological ornament. They unrolled classified blueprints and openly debated the tactical limitations of their arsenals specifically, the fatal flaw of radio-controlled torpedoes, whose Continuous Wave (CW) guidance signals could be easily located and destroyed by enemy jamming static. Hedy sat in silence, executing a high-velocity data harvest.
  • The Bicycle Exfiltration: Recognizing that her life was in terminal danger as the Nazi Anschluss loomed, Hedy orchestrated a daring escape. On the night of her exfiltration, she introduced a heavy sedative into her maid's tea, stole a servant's spare uniform to bypass biometric recognition, stitched her liquidated wealth in diamonds into the coat lining, and fled the estate on a heavy-framed bicycle under the cover of night.
  • The MGM Camouflage: Fleeing across Europe to London, she secured passage on the luxury ocean liner SS Normandie, where she executed a brilliant psychological bluff against MGM studio boss Louis B. Mayer, securing a massive contract and a new identity: Hedy Lamarr. While starring in box-office hits like Algiers, she converted her dressing room trailer and Hollywood Hills home into an unauthorized engineering laboratory.
  • The Player-Piano Cipher: When World War II broke out and German U-boat Wolfpacks began slaughtering Allied merchant shipping in the Atlantic, Hedy teamed up with avant-garde composer George Antheil. Remembering the torpedo jamming crisis from Mandl's dinner table, they engineered Frequency-Hopping Spread Spectrum (FHSS). By utilizing miniaturized, synchronized clockwork motors and perforated paper rolls modeled after player-piano ciphers, they engineered a radio guidance system that rapidly hopped across 88 distinct frequencies, making the signal mathematically un-jammable.
  • The Bureaucratic Burial: In June 1941, they filed Patent 2,292,387 ("Secret Communication System") and handed it to the U.S. government for free. The National Inventors Council validated its brilliance, but the U.S. Navy Bureau of Ordnance dismissed it as "too bulky," shockingly assuming they literally meant placing a physical piano inside a torpedo. The government seized the patent under the Alien Property Custodian and locked it in a classified vault, ordering Hedy to sell war bonds with a kiss instead.
  • The Ubiquitous Ghost: Decades later, during the Cuban Missile Crisis, the Navy quietly resurrected her architecture in solid-state transistors to secure anti-submarine sonobuoys. Today, that exact frequency-hopping blueprint forms the foundational backbone of modern Bluetooth, Wi-Fi, and CDMA cellular networks.

My full narrative non-fiction teardown of this incredible declassified history, THE SIREN'S CODE: The True Story of Hedy Lamarr, Secret Espionage, and the Code That Changed Modern Warfare (Book 6 of the Declassified historical series), is completely free to download on Amazon today only.

5 Upvotes

Hi everyone! I'm looking for readers for Midnight, the first book in my Farroway Investigations series.

Twenty-nine children vanished from one outback town. Now the dead want to be heard.

Ghost hunter Madelyn Farroway livestreams every case. When a grieving mother asks her to find out what happened to her eight-year-old son, missing for four years from the remote mining town of Wonira, it could be the case that makes her name. But she's brought along her sixteen-year-old brother, a brother she barely knows. Then a storm rolls in that won't move on.

Genre: paranormal mystery / urban fantasy, set in the Australian outback

Length: about 77,000 words

Free ARC Format:

ebook (EPUB, Kindle or PDF) through BookFunnel

Already published:

It's on Amazon and in Kindle Unlimited

Content warnings:

  • missing and murdered children, child abuse (not shown on the page), murder, possession, racism and colonial history

Spice: none (at least in this first book)

You'd be perfect if you enjoy ghost stories, investigators who deal with the dead.

All I ask is an honest review on Amazon and/or Goodreads within about four weeks, whatever you think of it.

Thanks so much!

I'm an Author! [Kindle] Greg of Despair, A Great Man Odyssey - Author is me - Free until 22 October - Satirical Epic

Thumbnail amazon.com
3 Upvotes

Blurb:

---
In a future where women dominate the world, and men survive only in isolated pockets of Australia, the Great Man Society sends a small group of dudes on a mission that obviously spirals into absurdity. From a vicious fight with a tuna fish that leaves no man untouched, to encounters with cannibal oil-riggers, feuding noble houses, and political intrigues in Los Angeles, the men confront a world both futuristic and oddly ancient.

Told through the eyes of a self-important historian who believes in his own psychic insight, Greg of Despair: A Great Man Odyssey is a satirical epic that combines adventure, quirky philosophy, and dark humor. The men navigate murder, maybe some marriage, brutally silly politics, and unexpected betrayals, all while pursuing a mysterious agent named Kurtis, whose secrets may or may not matter.

Laden with (and in large part propelled by!) satire, epic adventure, and philosophical reflection, this story unites the ancient and the absurd in a future as strange as it is unforgettable. (I certainly haven't forgotten it, and neither should you!)

Apollo! Arrange a meeting with the muses. We have things to discuss...

---

It was the first book I wrote, but the second book i finished editing and published. It is a bit of a strange book, but there it is. It bears some of that history, which to me makes it a bit of an interesting artifact. Personally, I think it's best in the middle.

Do you like quirky philosophical satire where it's never quite clear what it's making fun of? Well, if you do, it might be for you, maybe. I could technically mark it as science fiction, but it doesn't focus on those aspects at all. It's a satirical epic featuring adventurers and medieval city state politics, happening in the future but also with a kind of old fashion'ed feel. Not really sure what category it is in, but I therefore coin the term "Satirical Epic" as the genre

The book is slightly inspired by the Samuel Butler translation of the Iliad and Odyssey, because grandiose Victorian prose often makes me laugh. There's also some elements of something Plato's republic adjacent, and with many nods to pop culture, and even Heart of Darkness to some extent, though that's mainly for plot purposes rather than theme.

The culture of the men in Australia is a bit inspired by the Ancient Greeks, while the society of the women in America are a bit more modern, but also strangely medieval. I'd classify it as kind of medieval Italian city states meets archetypal American sort of culture.

Also: Men and women don't understand what men and women are, and this ignorance is never really resolved. That's another little neat thing about the book, I suppose.

What I'm saying is just that it is... worth reading? Yeah. It's worth reading. Maybe. Of course, it is. Sure. Go ahead and read it, I won't stop you.

  • Book 1 (Aether & Ash): FREE until October 19th!
  • Book 2: (Of Ashes and After) On sale for just $0.99 right now to celebrate the promo!

Born without Aether in a Realm carved by it, I was never meant to matter. While others rose as Hunters, binding Telmoria’s Aether-born creatures to their will, I scrubbed their halls and learned that hope was its own cruelty.

Until the Trial.

When a royal showcase of power spirals into chaos, a beast no Hunter can command turns on the crowd and chooses me. To survive, I do the impossible: I defy the Heir of Atlassian himself.

My defiance should have ended in death. Instead, it binds me to Damien Azarios - the Realm’s coldest blade, a sovereign-in-waiting who bows to no one. He should despise me. He should destroy me.

But he cannot stop wanting me.

As ancient beasts rise and Atlassian power trembles, our forbidden bond may become the spark that burns the world or remakes it.

If you love Carissa Broadbent’s high-stakes tournaments (The Serpent and the Wings of Night), Danielle L. Jensen’s ruthless royals (The Bridge Kingdom), and the lyrical magic of Margaret Rogerson (An Enchantment of Ravens), you’ll be swept away by Aether & Ash, the first book in the Reigns of Telmoria series.

One year after surviving the car crash that killed his wife, former Minneapolis detective Ben Kessler struggles to adjust to his new position as a beat cop in a small Minnesota town. When a disagreement with his sergeant lands him on a punitive assignment in nearby Lake City, he runs into not one, but two people from his past—Calvin, an ex-con he’d put behind bars five years ago, and Andrew, the man responsible for the death of Ben’s wife. He recruits the former to help him catch the latter, but it doesn’t take long for Ben’s demons to interfere and his plan to unravel.

Mistakes are made, lines are crossed, and before Ben knows it the tables are turned. Now framed and on the run, he finds an unlikely ally in Calvin, the only person who believes in Ben’s innocence. Together they must evade the very police force that Ben used to be a part of while racing to find any shred of evidence that might clear both of their names. If they fail, it’s not just Ben’s career on the line—it’s Calvin’s newfound freedom, and the only piece of himself that Ben has left.

A city cat. A country cat. One leash that refuses to let go.

Lina is elegant, proud and perfectly happy with her life: a warm bed, dinner on time and floors so smooth there are never any surprises. Then her human's suitcase appears in the bedroom.

Within hours, she has been hung in a grocery bag, locked in the dreaded carrier and driven to a house in the countryside, where she is tied by a leash to a big orange cat named Felix. Add angry wasps, a river that is much too deep, disastrous fishing attempts and one very opinionated fish.

A light, funny, warm-hearted story narrated by the most dramatic cat you will ever meet. About 15,000 words, short chapters, all ages. Standalone, no need to read Book 1.

Free on Kindle:
