DC celebrated the first anniversary of "The New 52" in September 2012 by publishing a number "0" of each original "New 52" title which act as prequels to the series and reveal previously unexplained plot elements. Gregg Hurwitz wrote the "0" issue. Hurwitz was approached by Daniel to write the "0" issue due to Daniel's busy schedule. To follow up on the "Night of the Owls" elements in "Detective Comics", Daniel wrote "Detective Comics Annual" #1 which was pencilled by Romano Molenaar and inked by Sandu Florea.
