"I see heads." / "And I see tails." / "It's all a matter of perspective" / "The same coin." / "A different perspective." / "Heads." / "Tails." / "Dead." / "Alive." - R. Lutece. Zootopia was once a much darker place. What happens when the Nick Wilde that is and the Nick Wilde that could have been switch places? Reality hopping shenanigans, that's what.

In this sequel to "A Study in Gold," Dr. Hopps returns to Zootopia after Christmas of 1881 and finds herself almost immediately caught up in another baffling case with her flatmate and friend, consulting detective Nicholas Wilde. After a mysterious and paranoid mammal sends a telegram begging for help, the two must put an end to a series of attempted murders before it's too late.

What if Judy and Nick hadn't swapped out the serum for blueberries? As Bellwether tightens her grip on the divided Zootopia, Nick is turned savage for real and committed to solitary confinement. But Judy isn't ready to give up on him, and soon the two are fighting for survival - not just against the world, but against each other. Set during/after an alternative ending to the movie.
