Lela, a curious fifth-grader, couldn't wait to solve the mystery of her missing lunchbox. She had packed her favorite peanut butter and jelly sandwich, a juicy apple, and a bag of crunchy carrots, but when she opened her locker, the lunchbox was nowhere to be found.

Determined to get to the bottom of this puzzling case, Lela began interviewing her classmates. She questioned her best friend, Samantha, who swore she hadn't seen the lunchbox. Next, Lela approached the class prankster, Ethan, but he firmly denied any involvement.

Just as Lela was about to give up, she noticed a trail of crumbs leading down the hallway. Following the breadcrumb clues, she discovered her lunchbox in the teacher's lounge, with a few bites missing from the sandwich.
