An archaeological dig in Cornwall has gone very wrong, very quickly. And Maria Kilbride has her hands full already, as the effects of the Injection begin to dig in. So Brigid Roth, her old comrade from the CCCU, gets hired to go to a stone circle in the middle of a moor, under a granite tor, to find out why a ritual murder might have torn a hole in the world. What is the Cold House? Collects INJECTION #11-15.
