There were two sets of images on the book object without a key: those on the paper accordion-fold tail and those painted on the wooden exterior surface. If the images on the accordion-fold tail were icons from the artist's life, did -- as the pile of keys among them indicated -- the images on the exterior surface point to the location of the key?
Recalling that one of the things painted on the outside of the book object was a vaguely familiar wide staircase -- probably on the outside of a large official building -- Caydance stopped on her way to Union Square to look at a staircase of a granite building directly across the street.
As she stood on the sidewalk, she noticed that as if it had been following her, an unmistakable 1957 Ford was forced by the dense stream of traffic to proceed directly past the street corner where she was standing.
