Once again Cantrell has set a cozy mystery - my favorite reading - in a horrifying time and place, with incredible results. Hannah Vogel first appeared in A Trace of Smoke as a Berlin crime reporter, and now lives in hiding as a travel writer from Great Britain (who performs the occasional job as courier/spy). In Poland to write an article, her strong sense of ethics leads her into danger when she interviews Jewish refugees forcibly deported from Germany. After that, there's no looking back as Hannah's fearlessness inadvertently involves here in one of the most horrific Nazi acts of the pre-war years: Kristalnacht. The historical milieu is haunting and exquisitely drawn, and Hannah's courage is inspiring. The mystery plot is clever and the pacing just right. I still hope for more of these brilliant books.
