The Appraisal Begins

A Specialist’s Assignment
A collection inventoried
Genghis Cohen undertakes to appraise Pierce’s extensive stamp collection. Oedipa initially regards the albums as another administrative burden rather than a source of meaning.
Expertise becomes consequential
Cohen’s close attention to small variations will transform the collection into one of Oedipa’s strongest bodies of evidence. His professional task joins estate work to the emerging mystery.
The Watermark Discovery

Irregular Stamps
A strange mark
Cohen shows Oedipa a Pony Express stamp whose watermark bears the muted horn. Additional stamps display deliberate design errors, including a misspelling.
A pattern with a past
The anomalies appear across issues separated by decades. Cohen cannot identify their maker, but the stamps suggest a sustained practice of covert marking rather than isolated mistakes.
The Expert Committee

Cautious Verification
Evidence handled delicately
Cohen consults other specialists and considers submitting the stamps to an expert committee. He is careful about authorization and uncertain about what the marks establish.
Knowledge remains provisional
Oedipa presses him about W.A.S.T.E., but the conversation becomes guarded. Even the collector’s expertise cannot turn the stamps into a complete account of the organization.
The Added Catalogue Entry

A Stamp in the Catalogue
A surprising listing
Cohen receives a Scott catalogue containing an inserted listing for a Tristero rapid-post stamp. The item’s provenance traces back to Zapf’s Used Books, a property associated with Pierce.
Evidence turns suspicious
The catalogue could support the stamp’s authenticity or be another planted clue. Oedipa sees that the same discovery can strengthen the mystery and deepen her suspicion of a setup.
Lot Forty-Nine

The Stamps Go to Sale
A final professional duty
Cohen helps bring the forged stamps to auction as lot 49, even as Oedipa suspects that a hidden buyer wants them. He is also tempted by other lots himself.
The inquiry at its threshold
Cohen accompanies Oedipa into the auction room, where the secret bidder may appear. His expertise has helped expose the evidence, but cannot disclose who will claim it.
