Hacker returns to Poddleville with a peace offering: a magnificent statue of the Mayor of Poddleville. But at the unveiling party, Hacker accuses someone of stealing the key to his recharger chair. The accused claims he’s innocent. Like Sherlock Holmes and Dr. Watson, the kids and Digit investigate the crime by interviewing eyewitnesses and recreating the crime scene.
