At 1:30 PM, a message was sent out. Some received it via text. Some got a phone call with a nondescript voice. Others found emails waiting for them in their inbox.
Regardless of the method, the message is the same:
I wish to speak with you. I will be at the stage in the park in 2PM.
Most people will know what stage is being mentioned: the impromptu one set up for the food festival judging taking place tomorrow.
