Summary
A innocent man was murdered in a warehouse for seemingly no reason and no leads to who his murderer was. Even the Batman couldn't find anything.
Ten years later, some evidence is found that opens the long cold case of this mysterious murder...and all evidence points to Jonathan Crane and Edward Nygma who have very recently been under the radar and suspiciously quiet.
Batman sets out to put the two behind bars for the murder, seeing as all evidence is against them, but his four youngest children; Tim, Stephanie, Duke, and Damian come across some odd inconsistencies and detials that throws the whole set of evidence into doubt. Other Rouges coming to their defense, or how Jonathan had still been a doctor at Arkham Asylum at the time and Edward had only newly become the Riddler, or how they hadn't even met each other yet, and Damian's friend from school starting to act odd.
Even more jarring is the new villain on the scene, the Reaper, claiming that the two are innocent and asking the four batkids for help to prove the Scarecrow and Riddler's innocence.
Are Edward Nygma and Jonathan Crane innocent? Will they end up behind bars? And who is this mysterious villain asking for help?
