The Case of the Missing Cookies

Ages 6-10 · 4 min read

On Saturday morning, Mom baked a tray of chocolate chip cookies and left them on the kitchen counter to cool. When she came back, three cookies were missing.

“A mystery!” said Priya, grabbing her notebook. Priya was eight, and she wanted to be a detective.

She wrote down the facts. Cookies baked at nine o’clock. Three missing by half past nine. Four people were home: Mom, Dad, her little brother Kai, and Grandma.

First, Priya looked for clues. On the counter she found a few crumbs and a smear of something sticky. On the floor, near the back door, there were small muddy prints.

“Kai has muddy boots!” she said. But Kai’s boots were dry and clean by the front door. He had been building blocks in the living room all morning, and Grandma had been with him.

Dad had been in the garden. His shoes were muddy, but his footprints were big, and these prints were small and round.

Priya knelt down and looked again. The prints did not have the shape of shoes at all. They had four little toes and a pad in the middle.

She followed the prints out of the back door, across the patio and under the hedge. There, curled up on an old blanket, was Biscuit, the neighbor’s puppy, with chocolate on his nose.

“Mystery solved,” Priya announced. “The back door was open, and the thief has four legs.”

Mom gasped. “Chocolate isn’t safe for dogs!” They called the neighbor right away, who took Biscuit to the vet just to be sure. Luckily, he was fine.

That evening, Priya wrote the final line in her notebook: “Lesson: Look closely before you blame someone. And always close the back door.”
