A murdered mentor. A hidden equation. A secret buried for centuries because some truths are too powerful to be set free.

Nathan Brooks has spent his life solving impossible problems. A brilliant mathematician, he's built his career on finding order where everyone else sees chaos.

Then his mentor is found murdered inside a locked office.

Written in blood beside the body are two words:

THE EQUATION

The research is gone. The evidence has vanished. The only clue the killers missed is an old brass key hidden in Nathan's pocket.

As Nathan follows a trail buried across decades, he uncovers a discovery so profound that The Continuum, a secret organization that has manipulated events from the shadows for centuries, will kill to keep it hidden.

Now they're coming for Nathan.

With the help of a former Continuum operative, he must uncover what his mentor died protecting before The Continuum buries the secret forever.

But the closer he gets, the more terrifying the truth becomes.

What if the world's greatest discovery wasn't hidden because it was dangerous... but because it would change everything we believe about what it means to live?

Perfect for readers of The Da Vinci Code, Dark Matter, and The Rule of Four, The Equation is an intelligent conspiracy thriller where murder, mystery, and philosophy collide in a race to expose the one secret humanity was never meant to know.

Once you see it, you can't unsee it.

Captain Sophie Allard once lived for the precision and freedom of flying fighter jets. Now, after one decision derails her military career, she is rebuilding her future as a medical student at a Denver trauma center.

Then a dying gunshot victim pulls her close and whispers a cryptic message meant for someone else.

By morning, the dead man’s belongings have vanished. Security footage raises more questions than answers. Sophie is accused of murder, suspended from the hospital, and targeted by professional killers who believe she possesses something powerful enough to expose them.

Her only possible ally is Kai Lovac, a legendary assassin who has spent three years hiding from the same shadow organization now hunting Sophie.

Lovac knows the rules of survival. Trust no one. Leave no witnesses. Never allow emotion to interfere with the mission. But his closest friend died protecting Dossier 1627, a secret report connected to the Third Estate, a covert syndicate that manipulates governments, military institutions, corporations, and criminal organizations from behind the scenes. Lovac needs the information the dying man gave Sophie. Sophie needs Lovac alive long enough to prove she is innocent.

Neither intends to trust the other.

Their uneasy alliance pulls them into a dangerous conspiracy involving hidden laboratories, encrypted messages, secret files, corrupt officials, and assassins bound by their own deadly code. Every answer exposes another betrayal. Every ally carries a hidden agenda. Every step toward the truth places Sophie closer to the organization that has been watching her far longer than she realizes.

As the Third Estate closes in, Sophie must decide how far she will go to reclaim her life and whether the man trained to kill without hesitation is the only person capable of keeping her alive.

Perfect for readers who enjoy intelligent female protagonists, reluctant alliances, secret societies, professional assassins, buried family secrets, and high-stakes suspense where trust can prove more dangerous than betrayal.

Now retired, Inspector Ramsay, of Miss Riddell Cozy Mysteries fame, has adopted a dog, Bracken, and taken to hiking the highest peaks of his native lands, Scotland and England. 

In the English Lake District, he and Bracken aid a young woman to escape her pursuers. She's been held captive for days before escaping. Ramsay is puzzled by this because he's heard on the radio, and read in the local papers, only that she'd run away from home. Had the kidnappers not demanded a ransom? Or were her parents and the police keeping that quiet, hoping for someone to give them a lead on where she was being held? This last didn't sit right with Ramsay, but nor did the idea that the kidnappers hadn't asked for a ransom. Ramsay begins to investigate, only to have the young woman run away from him. What's going on here in the quiet English countryside?

Every night at 3:33, he wakes frozen in terror.

At first, the dreams seem like sleep paralysis: frightening, but explainable. Then the images begin to repeat. A fog-covered field. An open grave. A figure lying at the bottom. Each night, the dream grows clearer, pulling him closer to a truth he is too young to understand and too afraid to ignore.

His grandfather, Eduard, has always been the safest person in his world — a quiet Estonian immigrant with pipe smoke in his sweater, old stories on his tongue, and secrets he never fully shared. But when tragedy draws the family back to his grandmother's house on Long Island, those secrets begin to surface.

Hidden journals. Stopped clocks. Strange warnings in a language he was never taught. And always the same hour.

As grief and fear blur the line between nightmare and waking life, he discovers that Eduard's stories about the "devil's hour" were more than folklore. There is a boundary between the living and the dead. Some people cross it. Some people see it. And something waits in the dark for those who face it alone.

Part supernatural horror, part family mystery, and part haunting meditation on love, memory, and loss, this is the story of a boy who inherits a terrifying gift — and must learn that courage is not always fighting the darkness.

Sometimes, courage means staying.

Delicately Disturbed is a dark psychological thriller that explores the terrifying consequences of buried guilt, fractured identities, and the monsters ordinary people can create.

Billy Frost thought the worst part of his week was a public confrontation that threatened the reputation of the driving school he built with his wife, Detective Evie-May Frost. But as his personal life begins to unravel, a far more sinister nightmare emerges. A man vanishes without explanation. Disturbing messages appear. Strange handmade gifts arrive on his doorstep. Then the bodies begin to surface.

At the center of the growing horror is Crimson—a calculating serial killer whose elaborate murders are driven by a decades-old secret shared by three childhood friends. Every victim is chosen for a reason. Every crime is part of a carefully orchestrated plan. As Crimson's twisted philosophy unfolds, the line between justice, revenge, and madness becomes increasingly difficult to distinguish.

While Evie-May races to stop an escalating killing spree, Billy is forced to confront painful memories he believed had been buried forever.

Someone has been waiting for the perfect moment to settle an old debt, and every revelation brings another victim closer to death.

It’s a classified registry of the world’s deadliest mercenaries — operatives embedded across governments, corporations, and criminal syndicates.

And it’s been stolen.

When a brutal homicide in the Catskills of New York exposes ties to a clandestine mercenary network known only as V.E.N.O.M. (Veiled and Exclusive Nation of Organized Mercenaries), NYPD detective Jake Penny is drawn into a covert conflict far beyond rural crime scenes and police tape.

As bodies surface and operatives mobilize to recover the stolen file, Jake is pulled into a shadow war he recognizes more than he should. Intelligence agencies scramble to contain the breach. A ruthless NSA handler begins tightening the perimeter. And someone inside the network believes Jake knows far too much.

The deeper he digs, the clearer the danger becomes: in the world of V.E.N.O.M., exposure isn’t containment.

It’s elimination. 

The Second Signature: An Edmund Finch Art Forgery Mystery - a cozy art forgery mystery by Edward Ellis

The Second Signature: An Edmund Finch Art Forgery Mystery - a cozy art forgery mystery by Edward Ellis
https://www.amazon.com/dp/B0GX36Q673

The Second Signature: An Edmund Finch Art Forgery Mystery is a clue-driven cozy mystery set in the world of museum conservation, Dutch Golden Age painting, and wartime provenance.

Houston, 1974. Edmund Finch is a senior conservator at the Museum of Fine Arts, a man whose life is built around routine, precision, and the patient study of surfaces. He is not a detective. He does not chase danger. He examines paintings, records what he sees, and trusts that enough attention will eventually reveal the truth.

When a seventeenth-century Dutch market scene arrives in his studio for restoration, Edmund expects a difficult but ordinary conservation project: darkened varnish, surface grime, old repairs, and the familiar uncertainties of attribution. The painting has long been catalogued as the work of an artist in the circle of Jan van Kessel the Elder — valuable, interesting, but not especially mysterious.

Then Edmund finds a pigment that should not be there.

A section of the sky contains titanium white, a modern material that could not belong to a painting from the 1600s. What first seems like a technical irregularity soon becomes something stranger and more deliberate. The painting is not simply damaged, misattributed, or poorly restored. Someone has left evidence inside it, and the evidence points back to 1943.

With the help of his friend Victor Holm, an art historian at Rice University, Edmund begins to follow the trail through archives, old records, provenance files, and the evidence held in the painting itself. The deeper he looks, the clearer it becomes that the forgery was not made simply to deceive. It was made to preserve something.

For readers who enjoy atmospheric mysteries without graphic violence, The Second Signature offers a slower, more thoughtful investigation, one built on observation, patience, art history, and the small details other people miss.

A cozy art mystery for readers who enjoy museum settings, historical secrets, provenance puzzles, no graphic violence, no explicit sex, and a methodical male protagonist who solves mysteries by looking more closely than anyone else.
