"Trapped with something that does not use doors."

January 1894. The Carpathian Mountains.
A snowstorm has buried the only road out.

Seven strangers have been lured to the Iron Crown Hotel by the dying Count Vrolok — paid to attend a gathering whose purpose none of them understand. When the Count is found dead the following morning, locked in his room with no sign of a killer, the guests realise they are not just snowbound.

They are trapped with something that does not use doors.

The soldier suspects the nun.
The doctor suspects the madman.
The madman knows exactly what is happening —
and no one will listen to him.

And the monster? The monster has been
in plain sight since the first page.

Told entirely through private journals, letters, medical reports, and desperate telegrams. A locked-room mystery wrapped inside a vampire horror — in the tradition of Bram Stoker's Dracula.
