Looking Forward To This
Detective Comics #877 comes out tomorrow:

It’s the second part of “Hungry City,” which has Batman (Dick Grayson) sleuthing out a mystery involving the brutal murder of a young woman whose body was found in the belly of a killer whale.
Last issue ended with his detective skills leading him into a deadly trap set in motion by some of the Gotham underworld’s newest and most fearsome players - including a slippery gun runner with titanium legs.
Batman: Gates Of Gotham
Batman: Gates of Gotham will kick off in May. The six-part miniseries by Scott Snyder will explore historic Gotham City and its many dark secrets.

From The Source: When a mystery as old as Gotham City itself surfaces, Batman assembles a team of his greatest detectives – including Red Robin, Owlman, I-Ching and others – to investigate this startling new enigma.
As clues are discovered and the mystery deepens, Batman’s team soon finds itself on a journey that explores different eras in Gotham’s history and touches upon notable Gotham families including the Waynes, Kanes, and Elliotts.
This miniseries spins out of recent events in the Batman titles and sets the stage for several exciting storylines in 2011. Additionally, this limited series touches upon mysterious story elements introduced in Grant Morrison’s Return of Bruce Wayne.
The Batman: Gates of Gotham miniseries will bridge Gotham’s past to the overall future of Batman. Issue #1 is set for sale on May 25.
