A Picture on the Wall
Art as possession
Prentice keeps a brightly colored Tibetan Mandala above his desk, appreciating its design more than its religious meaning. It sits among other works in his private collection.
A clue unnoticed
The image appears decorative to Prentice but holds spiritual significance for Elmquist. Their different readings make the same object a bridge between two worldviews.

Elmquist’s Diagram
A stated longing
Elmquist shows the boys a book illustration and says a mandala can aid meditation. He wants a guru to design one for him in India.
Knowledge without access
He describes Prentice’s Tibetan image despite claiming never to have entered the apartment. His knowledge becomes a clue to the apparent shadow.
A Contradiction Examined

A Contradiction Examined
The question of access
Jupiter Jones asks whether Prentice lent the Mandala for framing or discussed it with Elmquist. Prentice denies doing either.
A supernatural hypothesis
The unexplained knowledge supports the possibility that Elmquist observes the apartment while asleep. The Mandala becomes evidence not because of its symbolism alone, but because someone knows it in detail.
Meditation and Television

Meditation and Television
A modern ritual
Elmquist says he watches television without sound and studies the changing colors until he feels detached. Sometimes, he admits, he falls asleep and dreams.
The practical consequence
His habit offers a plausible route into the wandering experiences described at Ruxton University. A spiritual practice may produce unintended observation rather than deliberate intrusion.

The Object’s Two Lives
Art and instrument
Prentice’s Mandala is at once a treasured design and a clue to Elmquist’s strange access. Its meaning depends on whether it is viewed as possession or a tool for contemplation.
A broader contrast
The case places spiritual detachment beside the pursuit of wealth and collectible art. Neither perspective alone explains the crimes, but the contrast enriches the mystery.
