Sylvain Delahaye

Sylvain Delahaye — Né près de Paris, vit à Moyaux, Normandie

Sylvain Delahaye was born in Normandy, where he still lives today. A doctor of pharmacy, trainer, and quality auditor, he has long accompanied organisations in their pursuit of operational excellence. Writing, inherited from a family lineage of committed journalists, accompanied him in silence for years before asserting itself as a necessity. The Fifth Breath is his first novel.

Sylvain Delahaye was born in Normandy, a land of tides and hedgerows, and he still lives there, in Moyaux in the Calvados. This continuity with a territory is no biographical accident: it informs something of his way of inhabiting the world and working within it. Slow, demanding, attached to long seasons rather than sudden brilliance. He likes things that take time to ripen.

His initial training is scientific. A doctor of pharmacy from the University of Caen (2001), he completed his studies with a postgraduate diploma in Dietetics, Nutrition and Nutraceutics at the University of Besançon (2005). He later trained in Neuro-Linguistic Programming and hypnosis, becoming a practitioner and then a master practitioner, and obtained his ISO 9001 Lead Auditor certification (IRCA) in 2025. This diversity is not dispersion: it is the itinerary of a man who seeks, across different disciplines, to understand how human beings are built, damaged, and repaired.

His professional life reflects the same coherence. Pharmacist, sales manager of a parapharmacy he helped grow, trainer, consultant in management and quality of working life, certified auditor — Sylvain Delahaye has made accompaniment the guiding thread of his career. He now leads Qualio 3.14, a Qualiopi-certified training organisation he founded in 2023, and has co-directed the 1Audit2Pro consultancy since 2022, specialising in auditing and supporting training organisations. He also continues to practise independently in Lisieux, accompanying patients in their nutritional and dietary approach, particularly in the management of chronic conditions.

From this dual practice — the pharmacist who listens and the auditor who structures — he has drawn a simple conviction: genuine quality, whether organisational or human, cannot be decreed. It is built through patience, precision, and respect for the real.

Writing, for Sylvain Delahaye, is not a late vocation; it is rather an underground river long followed in silence. It is inscribed in his family heritage: his grandfather and great-grandfather were journalists, engaged in the intellectual and political struggles of their time. This quiet transmission long coexisted with professional life, before asserting itself as a necessity — that of putting into narrative what experience alone can no longer contain.

The Fifth Breath is his first novel. But around it unfolds a broader writing project, extending into several philosophical essays in progress — notably on the conditions of consciousness, on fear as a matrix of the living, and on what he calls, at the crossroads of science and philosophy, a scientific theology of consciousness. The novel and the essays nourish each other: one explores through fiction what the others work through argument.

He lives in Normandy, in Moyaux, where he continues to write — between the workshop of daily life and the wider horizon opened, at regular intervals, by the underground river.

The Fifth Breath was written over two and a half years. This duration is not incidental. It corresponds to the slowness demanded by a project that sought, from the outset, to articulate three rigours: historical rigour (the Ahnenerbe, the Reich's occult expeditions, the escape routes to Perón's Argentina, Anatolia, Tibet, the Andes, Jerusalem in 1948), geographical rigour (every place described was studied, mapped, documented), and interior rigour (every character had to be able to stand upright, with their flaws, their fatigue, their moments of grace).

The author wrote most often at night, during professional trips — in hotel rooms, apart from daily life, at the hour when fatigue drops one's defences. He says he lived the adventures of his characters alongside them. Walked with Aria and David across the Anatolian plateau. Kept watch with Don Anton in the cell where Lukas speaks the phrase that delivers him. Held, like Roke, the weapon placed beside sleep. This way of working — where the author stands at the level of his characters, without elevation — gives the novel that quality of presence which is its strength.
