Welcome, brave patriots! I’ll be your guide through the winding cobblestone streets of Philadelphia.

We have a bit of a riddle on our hands, and we need your sharp wits to solve it. As you move through our Mystery Walk, you will embark on a journey through the city by visiting 9 different clue signs, each representing a different location in historical Philadelphia. At each sign, use your cellular device to scan the QR code—this will allow you to hear the story clue from the local townsfolk, such as the blacksmith, the printer, and even a dockhand at the waterfront.

Listen closely to their stories! Each one holds an important detail to help us solve our mystery. With every audio clue you hear, you can cross a name off your list of suspects until only one remains. But hurry now, history is waiting!"
