Publisher's Synopsis
It's December 1922. Josine Young - the woman who introduced Jack Glennison to the otherworldly mysteries of Darkisle - is back in Manchester, on the run from the cult known as the Church of the Celestial Shadow. Christmas might be nearing, but the feeling is far from festive as it becomes evident that someone is out to kill the pair of them. With Manchester suddenly too dangerous, it's time to attend to some unfinished business on Darkisle....
The third book in the Glennison Darkisle Cases series takes us deeper into the world of ancient gods, deadly magic and terrifying monsters that we were introduced to in 'The Gathering of Shadows' and learned more of in 'Those Under The Hill'. Returning to Darkisle to help a former client, Jack is soon meeting with both friends and foes from his last trip to the island. And just what is behind the mysterious disease that is spreading across the town of Carnven? An atmospheric slice of 1920s detective noir with a British take on Lovecraftian horror, 'What Festers Within' sees Jack and Josine fighting for their lives as Darkisle is swept by blizzards, public unrest and a growing tide of fear - a fear that proves to be contagious....
