An antique pocket watch was reported missing from a locked study. The housekeeper said she dusted the room at noon, and no one else entered. The window was locked from the inside, and the heavy oak door was bolted from within. Yet, the watch was found inside a sealed glass jar on the shelf. How did it get there?
The housekeeper left the jar open while dusting
Since the housekeeper dusted the room at noon and handled items, she placed the watch into the jar, or the jar was unsealed at the time of dusting and later sealed.
