A city where the old rules return.
Edinburgh, 23 December 1869. Inspector Malcolm Fraser is called to a corpse found in a room locked from the inside: three wounds that bled after death, an expression of absolute terror, and no humanly possible way out.
The case brings together four figures: Fraser, a sceptical inspector; Lyle MacLintock, forensic physician and former comrade-in-arms; Doves, a young constable; and Eleanor Withmore, a medium active in Edinburgh's spiritualist circles.
Each understands a different part of the case. None understands enough.
As the deaths spread, the investigation abandons criminal logic and enters a forgotten system of European belief: the Wild Hunt, soul-doubles, forbidden texts, and rules the modern city no longer knows how to follow.
