Elizabeth Peters: Borrower of the Night (UK 2007)

From the Publisher:
A missing masterwork in wood, the last creation of a master carver who died in the violent tumult of sixteenth century Germany, may be hidden in the medieval castle in the town of Rothenburg. The prize has called to Vicky Bliss, drawing her and an arrogant male colleague into the forbidding citadel and its dark secrets. But the treasure hunt soon turns deadly. Here, where the blood of the long forgotten stains ancient stones, Vicky must face two perilous possibilities: either a powerful supernatural evil inhabits the place...or someone frighteningly real is willing to kill for what Vicky is determined to find.
