Second in the series (#1 here).
Still involved with the werewolves but the mystery here centers around the local vampires and their seethe. Very spooky stuff!
Some neat religious imagery with Mercy insisting on wearing a lamb necklace instead of a cross: “I don’t wear a cross. As a child, I’d had a bad experience with one. Besides, a crucifix was the instrument of Our Lord’s death — I don’t know why people think a torture device should be a symbol of Christ. Christ was a willing sacrifice, a lamb, not a cross for us to hang ourselves on; or at least that’s my interpretation.”
