The Golden Fang

[Dave Monroe]

... a mysterious entity known as the Golden Fang, which may only be a
tax dodge set up by some dentists.

At the heart of all the divergent plots is something called The Golden
Fang. Pynchon keeps its identity mysterious, indeterminate. The Golden
Fang may be a luxury yacht used for drug smuggling, money laundering,
kidnapping and torture; or it could be a holding company used by
dentists in connection with a tax dodge scheme; or possibly a south
Asian heroin cartel, or a funny farm for the rich, or all these
things.

Whatever it is, The Golden Fang has its teeth sunk deep into the era’s
feel-good zeitgeist, and Sportello can sense it’s sucking the country
dry: “Was it possible, that at every gathering—concert, peace rally,
love-in, be-in, and freak-in, here, up North, back East,
wherever—those dark crews had been busy all along, reclaiming the
music, the resistance to power, the sexual desire from epic to
everyday, all they could sweep up, for the ancient forces of greed and
fear?”

The story features Gaston Max, a Parisian criminal investigator and
mastery of disguise, and his battle with Mr. King, a master criminal
