Winner of the 2021 McIlvanney Award

Ian Rankin's Choice for Both Best Mystery Book of 2021 (PBS) and Best Books of the Year (New Statesman)

From international best-selling author Craig Russell comes a modern Gothic masterpiece.

Edward Hyde has a strange gift - or a curse - he keeps secret from all but his physician. He experiences two realities, one real, the other a dreamworld state brought on by a neurological condition.

When murders in Victorian Edinburgh echo the ancient Celtic threefold death ritual, Captain Edward Hyde hunts for those responsible. In the process he becomes entangled in a web of Celticist occultism and dark scheming by powerful figures. The answers are there to be found, not just in the real world but in the sinister symbolism of Edward Hyde's otherworld.

He must find the killer or lose his mind.

A dark tale. One that inspires Hyde's friend...Robert Louis Stevenson.
