By Alex Batts — The Arkham Knight story arc in Detective Comics wrapped up a few weeks back, excellently introducing the character to the mainstream comics continuity. With the closing of one arc starts the beginning of another. Detective Comics #1006 is part one of a new arca called “There Will Be Blood,” and it sees Jim Corrigan and macabre The Spectre character in Gotham City for a grizzly murder mystery in which the Vengeance of God seeks out the help of the World’s Greatest Detective.
