The script by Constantine writer Ray Fawkes contains much of interest. The revelations that Batman has enough Nth Metal to make a batarang and that it can be used to disrupt ectoplasmic figures is but one of the more fascinating bits of trivia this issue has to offer. I also liked the idea that the normally unflappable Alfred is made uncomfortable by Master Bruce's mystic associates or that weird things happen to mirrors around The Spectre.
The artwork by Gates of Gotham artist Trevor McCarthy is a suitable fit to the script. McCarthy's figures are oddly blocky and seem better suited towards a Vertigo series than the world of Batman. Nevertheless, this distinctive style is gripping and properly spooky when it needs to be.
