By Alex Batts — Detective Comics #1012 sees the Mr. Freeze story arc finally begin in earnest. This is a story that has been teased and built up in the closing pages of recent Detective Comics issues and has now taken center stage. Regular series writer Peter Tomasi is rejoined by penciler Doug Mahnke, inker Jaime Mendoza, colorist David Baron, and letterer Rob Leigh. While Christian Duce did a great job with the art for the previous arc, it’s a welcome sight to see Doug Mahnke back on a Batman book.
