Someday soon I'll do a little editing and splice the prologue audio onto the existing Chapter One audio, and take out the little end section with Copper and Vallan (which is now mostly redundant). Then it will match the PDF.
For now, here is the audio for the prologue in MP3 format. Find it on the Novel page.
And the audio for the exciting "Marshals & Madmen" (chapter five) is coming soon!
