The back-up story by James Tynion IV will offer chills and surprises to all. Eerily illustrated by long-time Daredevil artist Alex Maleev in his usual shadowy style, this story depicts a Superman/Batman team-up in the days following Damian Wayne's death. It spoils little to say that the case proves to have a supernatural element to it and it is an interesting juxtaposition to see the more realistic Dark Knight Detective and the magic-vulnerable Man of Steel suddenly pressed into a situation neither of them is fully capable of handling.
If you're only going to read one Batman book a month, this is the one to get. The writing in both stories is always impressive. The artwork is gloriously grotesque in a Gothic fashion that perfectly suits the world involved. Simply put, this is a damn fine book.
