Inspector Rostnikov is a Russian bear of a man, an honest policeman in a very dishonest post-Soviet Russia. Known as 'The Washtub,' Rostnikov is one of the most engaging and relevant characters in crime fiction, a sharp and caring policeman as well as the perfect tour guide to a changing (that is, disintegrating) Russia. Surviving pogroms and politburos, he has solved crimes, mostly in spite of the powers that rule his world. In People Who Walk in Darkness, Rostnikov travels to Siberia to investigate a murder at a diamond mine, where he discovers an old secret—and an even older personal problem. His compatriots head to Kiev on a trail of smuggled diamonds and kidnapped guest workers, and what they discover leads them to a vast conspiracy that not only has international repercussions but threatens them on a very personal level.
