The smell of burnt croissants and stale cinnamon sticks clung thickly to the old, frayed diner’s cold sticky linoleum floors. When Mia pushed open the door at six a.m., her shoes squeaked across the damp sawdust-strewn boards near the register. Just behind the food prepping counter, a limp figure lay still beneath a dazzling spatter of dark, crusted sticky substance. Mia recognized the limp figure as Tom, the quiet regular who drank a black coffee and ate a muffin daily. Her throat tightened unexpectedly when she spotted the cracked ceramic mug that Tom brought from his own kitchen sitting empty. Her fingers fumbled for the diner’s landline as she stepped quietly past the sticky pine table where Tom usually sat.
