She was eager to show off the new sourdough recipe she had perfected. She was going to surprise her mentor, Chef Dubois, with a loaf. He wasn't there. No lights were on. No scent of baking filled the air. Only a tiny note with a simple message: "Gone. Best of luck, Sarah." A strange quiet settled around her.
