Those are called Courier’s,
I have little understanding. Couriers in Jeremiah spread the message that Babylon would fall and ones in Esther said Ahesverus was going to do something (kill the Jews? I can’t remember. She had to fool and kill Haman to save them at some point) and I guess they carried letters on horseback. The Bob Dylan (and later Jimi Hendrix) song All Along the Watchtower may have been about Babylon but no one is sure.
Can you explain more? Was Maxine serious or delusional (or both).
Thanks in advance.
