Rusputin’s Revenge
by John Lescroart (Dutton, 1987); audiobook read by Tim Baltz (Brilliance Audio, 2011)
A mystery rich in period detail but lacking a detective. Set in the Russia of Tsar Nicholas II, narrated by naïve French spy Jules Giraud and nominally featuring the son of Sherlock Holmes, this muddles along nicely enough until its absurd dénouement.
