A third-season story, described by the author as a novel in two parts: Ashes of Yesterday and A Sanctuary of Shadows.
A mysterious woman whom tunnel kids call 'the witch' - apparently a deranged street person - has been luring the children with gifts, some of them expensive. Vincent is troubled and suspicious of the woman's intentions. As Diana begins to try to learn who the woman is and why she's so interested in the children, she discovers a fact about the tunnels' past which upsets Vincent even more. Meanwhile Diana has been investigating a case involving a serial killer. That plot thread dominates the story's second half.
Diana and Vincent, by the end, are becoming much more intimate.
