Adventure Hook: Jail Time

One or more of the PCs wake up in jail with no recollection of the preceding night. Before they can demand a lawyer, to be released or talk to a judge, an officer of the jail announces that it was all one big mistake and releases the PCs from jail without answering any of their questions. As they walk around town after their release, parents pull their children closer and they hear whispers of, “It’s them.” and “I can’t believe they were released from jail”.

What did the PCs do? Why were they released from jail so quickly? Are they exonerated? Was it a mistake? Will they be arrested again and hounded by the authorities?
