The Case of the Missing Cupcake

The Scene: A bustling office kitchen. A plate sits empty, where a delicious-looking cupcake once resided.
The Suspects:
Beatrice: Known for her love of sweets, especially buttercream frosting.
Charles: Always on a diet, but secretly has a weakness for sugary treats.
Daniel: Frequently seen late at night, leaving the office with suspicious crumbs on his clothes.
Emily: Recently declared her dedication to a healthy lifestyle, but temptation can be strong.
The Clues:
A faint scent of chocolate lingers in the air.
Beatrice has a meeting at 10:00 AM, the exact time the cupcake disappeared.
Charles has a gym membership and religiously tracks his calorie intake.
Daniel was the last person in the office the night before.
Emily's desk is spotless, unlike her usual pastry-filled haven.
Who stole the cupcake?

Solution: The culprit is Daniel. While everyone else has an alibi or motive that contradicts their actions, Daniel's late-night presence and crumb-covered clothes point directly to him. Remember, the scent of chocolate lingered, and Daniel was the last one in the office, leaving ample opportunity to indulge before leaving the crumbs as a red herring.
