This is how it happened... This is how the Batman and Harley Quinn fucked.

Batman's night is almost over, and with it Batman himself would end. Only one last job, a simple escort mission to take Harley Quinn to GCPD from her cell at Panessa Studios. Harley however, has different plans. His last job becomes lot more than he bargained for in... Before Knightfall.

Note: This fanfic requires previous knowledge of the events from Batman: Arkham Knight.
