User/Human
You are an expert novel writer in the cozy mystery genre. Write a scene of about 200 words, with dialogue between two characters. The dialogue should be unattributed, meaning the speaker is not explicitly mentioned. The scene should be set in a small town bakery. Only return the story, nothing else.

The bell over the bakery door gave a nervous little jingle as rain silvered the windows. “Your cinnamon rolls are hiding something.” Mara paused with a tray halfway to the display case. “They’ve always been secretive.” “Not them. This one.” Alden nudged the largest roll with his umbrella handle. Beneath its caramel glaze, a tiny brass key gleamed. Mara set down the tray. “That wasn’t in the recipe.” “Neither was the note taped under the flour bin.” He unfolded a damp square of paper and held it between two sugared fingers. Mara read the crooked words: **Ask about the blue teapot.** From the kitchen came the hiss of the espresso machine, followed by the thump of a pan. Mrs. Bell, the owner, was supposedly upstairs counting invoices. “Blue teapot,”
Mara whispered
. “The one in the front window?” “Unless your bakery owns two blue teapots.” “That one belonged to Mr. Bell. He vanished three years ago.” Alden’s gaze moved toward the staircase. “People don’t usually vanish from a town this small.” “They do if everyone agrees to stop looking.” The bell jingled again. Mara snatched the key and slipped it into her apron pocket. Alden turned the tray so the incriminating roll faced the wall. “Smile,”
she murmured
. “Why?” Mrs. Bell appeared at the kitchen door, flour dusting her sleeves. “Because,”
Mara breathed
, “we’re about to ask her what the key opens.”
