Shoe nr. 42

Paul Fifth is baffled why he didn’t turn down Hugo’s proposal to spend spring break on a trip searching for flying-squirrel nesting sites with a local professor of zoology. It’s nice to hang out with Ats and Minna, of course, but tramping through a dense forest and hunting for yellowish droppings under big aspen trees isn’t quite his cup of tea. Then, he discovers a little silver heart amidst the moss. None of them has any idea how it could have ended up so deep in the woods. When the kids also find strange ropes tied to the trees and size-42 boot prints nearby, they have no choice but to open a new case file.
