About this book:

In Victorian London, Hugh Thorne, a rationalist engineer, is hired by a skeptical academic to infiltrate Holloway House and expose the fraudulent mechanisms of its high-society séances. He soon becomes entangled with the medium, Evelyn Audley, a fragile young woman whose manifestations—ranging from agonizing vocal possessions to physical objects carved into wood—defy easy mechanical explanation. As Hugh seeks a scientific solution for these phenomena, he discovers that the house is a crucible of repressed grief and "forbidden disclosures," where the sitters’ deepest secrets are leveraged by the proprietor, Mrs. Hallowes, for social and financial control.

The investigation shifts from physics to psychology when Hugh uncovers the existence of Marcus, Evelyn’s deceased brother, whose protective and aggressive spirit acts as a volatile "anchor" for her abilities. Hugh realizes that the séances are not merely parlor tricks but a sophisticated form of emotional manipulation; specifically, a wealthy publisher named Mr. Vane has contracted the house to turn Evelyn into a conduit for a non-consensual romantic declaration. Bound by a growing attraction and a mutual need for truth, Hugh and Evelyn form a "pact of silence" and a "symmetrical inquiry" to dismantle Mrs. Hallowes’ operation from within, using the very tools of the séance—logic, leverage, and secret correspondence—to secure Evelyn’s legal and personal freedom.

After a series of high-stakes confrontations, including the exposure of a theatrical rival medium and the retrieval of a hidden diary from Evelyn's traumatic past, the pair successfully shutter Holloway House. They transition into a quiet, domestic life in Bloomsbury, where Hugh continues his engineering and Evelyn pursues botanical research. By reclaiming their own history and refusing to let their private desires be commodified, they transform the "medium’s price" into a foundation of material honesty. The story concludes with the ultimate victory of the living over the dead, as they lock away the "Black Ledger" of their secrets, proving that the most durable structures are built on unburdened consent rather than spectral illusion.
