Burn, Witch, Burn! / Creep, Shadow, Creep!

In Burn, Witch, Burn, a man dies an agonizing death from an undiagnosed disease whose only symptoms are microscopic phosporescent globes in his blood, while Dr. Alan Carnac is drawn into a forbidden netherword of horrific secrets, from which he may never escape in Creep, Shadow, Creep! Original.
