Three additional hints about the previous hint.
Here are a few more hints.
(1) The previous hint has nothing to do with the novel’s plot.
(2) The building on the left is a very specific building, and was chosen very deliberately.
(3) The middle image is indeed of a crib, but there are also other words for cribs. Also, we drew a circle around it for a reason. In fact, the circle may or may not have to do with the building on the left.
Think outside the box!
