It is September, 1950 and P. I. Jack LeVine has just pulled himself out of a year-long depression triggered by his father's death. He has re-invigorated his life and re-decorated his Broadway office when a high-strung second violinist from the NBC symphony walks through his newly-painted door and insists that the great Maestro Arturo Toscanini has vanished and that the orchestra is being led by an imposter. From this point on we are drawn into a violent and high-stakes investigation that will lead LeVine from the executive towers of NBC to decadent Havana and then to a raw desert town called Las Vegas. Along the way he uncovers an elaborate scheme involving the fiddler's gorgeous daughter and winds up rubbing shoulders with the fabled likes of Lucky Luciano and Meyer Lansky. Tender is LeVine then rockets to a hair-raising conclusion with a murderous cross-country chase as LeVine and Maestro Toscanini make a desperate run for their lives.
