Baldwin Furnshill and Bailiff Simon Puttock have been granted leave to go on pilgrimage. Together they travel across Europe to Portugal, but danger seems to follow them even this far afield, as they are among the first on the scene when a beautiful young girl is found brutally raped and murdered on the hillside of Santiago de Compostela. Baldwin and Simon lend their investigative skills to the ensuing enquiry headed by the local pesquisidore, Munio. With so many keen minds on the case it can only be a matter of time before the culprit is found. But they are reckoning without the unexpected appearance of a face from Baldwin's past - a face which looks set to threaten both the investigation and, it seems increasingly likely, Baldwin's very future.
