Detective Allen Silver squinted through his taped-up glasses at the forensic evidence from the heist, and agreed it seemed to be an open-and-shut case. The bank manager's shifty son's fingerprints were all over the safe, and his night-at-the-symphony alibi wasn't checking out. Silver knocked a stack of papers onto the floor as he leaned over the desk, drawing stares from the nattily dressed bank employees.

Silver plucked an antacid pill from his overcoat pocket, scratched his rumpled hair, and failed to suppress a burp, drawing more stares. The rumpled detective pondered what his gut was trying to tell him.
