Both of my thriller series – the Alex Demarchelier and the Helen Dillon series - can be enjoyed on their own, yet they’re intriguingly linked, with characters who move between the two worlds. I hope they’ll bring you pleasure.

Vivien Gibson

The woman who is always the victim in her own story.

Vivien is charismatic when she chooses to be, relentlessly entitled, and incapable of accepting responsibility for the harm she causes. She rewrites events until every crime becomes self-defense, every consequence becomes persecution, and every person who resists her becomes an enemy.

What makes Vivien dangerous is not flawless planning. It is her absolute belief that she deserves whatever she wants. She lies with emotional conviction, draws others into her grievances, and survives setbacks by reinventing herself once again.

Vivien is the “beloved” villain in the Alex Demarchelier series, a character readers love to hate.

Andreas Gershwiller

He does not need to control everyone. Only the person who controls everyone else.

Andreas is a criminal strategist who studies fear, greed, shame, ambition, and longing as meticulously as Helen studies computer systems. He rarely forces people to act. Instead, he identifies what they want and crafts a path that seems to lead them there—to his advantage.

Elegant, patient, grandiose, and profoundly dangerous, Andreas regards other people as pieces in a design only he can fully see. Prison, exposure, and defeat merely change the location from which he operates.

His conflict with Helen is both strategic and deeply personal. He wants to defeat her—but he also seeks recognition from the one person capable of grasping the scale of his mind.

With the exception of The Wall, Andreas plays a significant role in both series.

Collin Frey

The steady presence behind Helen’s most dangerous battles.

Collin, who debuted in The Wall, is an investigator and strategist whose calm exterior masks fierce determination. Physically imposing yet emotionally perceptive, he respects Helen’s independence while staying alert to dangers she would rather face alone.

He brings patience, institutional knowledge, and practical judgment to complement Helen’s technological brilliance. Their partnership works because he does not try to diminish or rescue her. He trusts her abilities—and stays beside her when those abilities put her in danger.

Perry Lowell

An entrepreneur who enters politics—and discovers how difficult it is to protect a family from power.

Perry is intelligent, optimistic, and more comfortable building businesses than engaging in political theater. His ambition stems from the belief that institutions can be improved, yet the presidency exposes his family to enemies who are willing to use love, history, and vulnerability as leverage.

His relationship with Alex is grounded in affection, partnership, and their private commitment to stay “One” when external pressures threaten to divide them.

Jasmine

Elegance on the surface. Intelligence operations underneath.

Publicly known as a glamorous gallery owner, Jasmine is a former intelligence operative with extensive international connections and a security organization staffed by exceptional agents. She translates concern into action almost instantly and meets danger with pragmatism, loyalty, and confidence.

Jasmine connects naturally with both series and offers a lively contrast to Helen.

Kate (The Curator)

Kate appears only in The Curator for now. She is a murder witness, an art curator, and a woman living under a new identity. She rebuilds her life piece by piece—until the criminals from her past enter the world she created.

Nora (Nemesis)

Nora Alden is another book-specific protagonist. She is a freelance journalist, a devoted mother, and an unlikely infiltrator. Guilt pushes her toward the truth. Rage takes her farther than she ever believed she could go.
