A secret compartment at the end of the book houses a removable page with four miniature books. There is no keyhole, but the copper panel swings open when the key grabs a rare earth magnet hidden on its right-hand edge.
The text in pencil is the opening lines of a poem by the artist (see below).
And knowing one lie and one truth
equals one truth and one lie,
you can enter the gates of heaven,
having phrased your challenge correctly.
In this world no dilemma
falls away so cleanly,
like sliced halves of an onion,
the way we liked to imagine heaven
with its concentric rings.
