In the best tradition of Batman: Year One, this third book in the Gotham Central series continues the film noir makeover of the Batman mythology! When the Mayor is assassinated in his own office by a sniper, Gotham City is hurled into a nightmare of panic and fear - all the more so when the killer turns out to be the Joker! The Gotham City Police Department have no choice other than to call in Batman, an act which shakes their confidence to the core. But can even the Dark Knight stop the Joker's murderous rampage? From the award-winning creative team of Greg Rucka (The OMAC Project) and Michael Lark (Terminal City) comes another tense, hard-hitting thriller!
