It may be April Fools' Month, but things are getting very serious as the 13-issue maxiseries continues! In Gotham City, the Calendar Man sets out to prove that he's nobody's fool. Where has he been since breaking out of Arkham and why is the answer bad news for Batman?
Plus, as the Freak/Mob war escalates, everyone is picking sides...so who gets the Joker?
