Cold autumn rain slicked the cobblestones outside the quiet corner bakery just as I pushed open its chipped wooden door. The sweet tang of burnt almond croissants curdled instantly when my gaze fell on the crumpled figure behind the counter. I recognized the frayed linen apron draped over the shoulders as the one the shop’s owner wore every single day. A shaky young barista huddled in the corner by the pastry case and kept muttering about a tall masked stranger. I reached for the notebook tucked inside my inner coat pocket and noted every small detail I could spot now.
