The Case of the Curious Cookie Caper

The Scene: A group of friends gather for a cozy evening, enjoying warm cookies and conversation. Suddenly, the lights flicker and go out. When they return, one of the delicious cookies is missing!
The Suspects:
Amelia: Known for her sweet tooth, but claims she was busy chatting during the outage.
Ben: Not a big fan of sweets, but was seen leaving the kitchen right before the lights went out.
Chloe: Has a history of sleepwalking and is known to wander into the kitchen at night.
The Clues:
There are no crumbs or bite marks around the missing cookie.
The window near the kitchen is slightly ajar, but there are no signs of forced entry.
Ben's phone flashlight was left on the counter, illuminating a faint trail of flour leading from the kitchen door to the living room.
Who stole the cookie?

Solution: Chloe, the sleepwalker, is the culprit. While sleepwalking, she took the cookie but didn't eat it (no crumbs or bites). The ajar window is unrelated, and the flour trail was left by Chloe's sleepwalking movements, not Ben leaving the kitchen.
