It was a rainy afternoon when Sara, a curious second-grader, stumbled upon a mystery. The delicious smell of freshly baked cookies wafted through the air, but when she went to grab one, the plate was empty!

Sara knew she couldn't have been the only one who noticed the cookies. She decided to investigate, hoping to find the culprit and get to the bottom of this tasty disappearance.

First, she questioned her younger brother, who always had a sweet tooth. "Did you eat the cookies?" she asked sternly. He shook his head, claiming he'd been in his room the whole time.

Next, Sara interviewed her parents, who were equally surprised by the vanishing treats. "We just took them out of the oven!" her mom exclaimed. Her dad scratched his head, equally puzzled.

As Sara continued her investigation, she noticed tiny paw prints leading from the kitchen to the living room. Following the trail, she discovered the family's puppy, Biscuit, happily munching on the last crumb.

Sara couldn't help but giggle. She should have known the playful pup was the culprit all along. From that day on, she made sure to keep a close eye on the kitchen whenever there were fresh cookies around.
