the interred Masters
only those lawyers, Avril, Disney Leith, and perhaps Mario know that the cartridges were, in fact, along with his case of special lenses, interred right there with J. O. Incandenza’s dead body
Context
The grave as the family's sealed vault, and the guest-list of who holds the key is the family's information map. The most sensitive Masters — Clipperton's suicide footage and other cartridges "designated Unviewable by testatory codicil" — plus Himself's case of special lenses lie buried in the bronze casket with the body itself, in the Mondragon family plot in L'Islet Province. And the circle of those who know is tiny and telling: the attorneys, Avril, Disney Leith, "and perhaps Mario" — not Hal, not Orin. The dead father's most dangerous work is literally interred with him, in the widow's ancestral ground, its existence a secret held by the mother and a couple of intimates. The Incandenza secrets aren't just kept; some are buried, in a grave that doubles as the family archive.
