The notebook behind the wall

A notebook hidden inside a wall.
A woman who vanished in 1934.
A secret someone is still willing to kill for.

While renovating a neglected Paris apartment, Mathieu Tersen breaks through an old plaster wall and discovers a small red notebook sealed inside a hidden cavity.

Its first entry is dated February 7, 1934.

The notebook belonged to Anna Delmas, a young woman living under a false identity while fleeing Gabriel Vauthier—a charming, influential man whose obsession concealed something far more dangerous than rejected love.

Anna had uncovered a network of respectable men who used the law, medicine, and family influence to manipulate inheritances, erase inconvenient witnesses, and make disappearances look perfectly ordinary.

She left behind a trail.

A photograph.
A numbered key.
A list of names.
And evidence powerful enough to destroy a dynasty.

With the help of Léna Sorel, Mathieu begins following Anna’s clues through forgotten Paris archives, an abandoned railway locker, a sealed room, and a succession of crimes buried beneath decades of silence.

But the deeper they dig, the clearer one thing becomes:

The people who protected the Vauthier secret never truly disappeared.

And now they know Mathieu has found the notebook.

The Notebook Behind the Wall is an atmospheric dual-timeline mystery combining historical suspense, buried family secrets, a slow-burn contemporary romance, and a haunting investigation into the crimes respectable people learn to hide.

Perfect for readers who enjoy:

• historical secrets;
• old diaries and hidden documents;
• Parisian settings;
• cold cases;

Some secrets are buried in walls.
Others survive inside families.
