M. M. Kaye - (2012) - Death In Berlin (mystery)

Set against a background of war-scarred Berlin in the early 1950s, M. M. Kaye's Death in Berlin is a consummate mystery from one of the finest storytellers of our time.
Miranda Brand is visiting Germany for what is supposed to be a month's vacation. But from the moment that Brigadier Brindley relates the story about a fortune in lost diamonds—a story in which Miranda herself figures in an unusual way—the vacation atmosphere becomes transformed into something more ominous. And when murder strikes on the night train to Berlin, Miranda finds herself unwillingly involved in a complex chain of events that will soon throw her own life into peril.
