Corporate hijinks mar the breathtaking scenery of the Himalayas—and set the stage for murder—in this Golden Age mystery from the author of Bengal Fire.   A construction overseer for Blenn Engineering Works, Paul Woodring, thinks he’s below the notice of Calcutta business mogul Alexander Blenn, but his singular skills are needed for a delicate mission: renewing a twenty-year-old concession that gives Blenn exclusive rights to develop mechanical transportation and resources in an Indian state near Darjeeling. But before Woodring steps on the train to the mountain city, Blenn goes missing and his general manager is murdered. Enter Insp. Leonidas Prike of the British CID . . .   Aboard the train climbing its way to Darjeeling is Prike and a raft of suspects including Woodring, Blenn’s niece and sole heir, a German botanist and Nazi party defector, an inveterate drunk, a Russian count, an engineering superintendent, and a mysterious dark-eyed woman. It will take all of Prike’s deductive skills to discover a motive and means for murder at the top of the world . . .
