Inspector Drake inspected a ransacked study. Drawers were pulled out, papers were strewn across the floor, and books were knocked off shelves. The homeowner claimed thousands of dollars in cash hidden inside a hollowed-out dictionary was stolen. Drake noticed that every single book on the floor had its spine facing upward, except for the dictionary, which lay face up with its cover open. Drake knew the robbery was staged. Why?
When books fall randomly, they land in random positions, but the dictionary was intentionally placed open.
In a chaotic, random ransacking, books fall haphazardly. The specific dictionary containing the money being conveniently open and face-up exposes that the owner staged the break-in to find their own hidden cash.
