Detective Thorne inspects a haunted manor where a rare coin vanished from a locked wooden chest. The owner claims a ghost extracted the coin through the tiny 1-inch keyhole without unlocking the chest. Thorne inspects the keyhole closely and sees small wood shavings curling outward toward the exterior. Why does Thorne conclude the chest was unlocked and tampered with manually?
Wood shavings curling outward prove a hole was carved or drilled from the inside toward the outside, which requires opening the chest first.
Drilling or cutting from the outside pushes shavings inward; outward shavings mean the chest was open when the hole was modified from the inside.
