A priceless diamond was stolen from a glass display case. The guard swore nobody entered the room, yet the heavy velvet curtains swayed, the window was wide open, and there was a puddle of water directly beneath the sill. It hadn't rained all week. How did the thief get it without walking in?
A trained falcon or bird.
The puddle of water indicates ice melting (perhaps carried by a bird or from a high-altitude flight), and a flying animal could enter through the high open window without walking into the room.
