Thought to be hallucinogenic and banned globally for a century, absinthe is once again legal and popular. Yet it is still associated with bohemian lifestyles, just as when it was the favorite drink of avant-gardists like Toulouse-Lautrec and Van Gogh and Baudelaire. And today, when vintage, pre-ban bottles are discovered, they can sell for exorbitant prices to private collectors. But such discoveries are increasingly rare.

Which is why the absinthe demimonde of rich collectors was electrified when a mysterious bon vivant claimed to be in possession of a collection of precious, pre-ban bottles.

Is his secret tranche of 100-year-old bottles real? And just who is the shadowy person selling them? And what about rumors of another secret cache, hidden away in an Italian palazzo?

Journalist Evan Rail sets out to discover the truth about the enigmatic dealer and the secret stashes. Along the way, he drinks with absintheurs frantically chasing down the pre-bans, visits modern distillers who have seen their status rise from criminal bootleggers to sought-after celebrities, and relates the legendary history of absinthe, from its birth in Switzerland through its coming of age in France, and on to its modern revival.
