Where did he go?
Batman as in the comic book series is in good hands as far as I can see. Tony Daniel's writing skills have really shined in these last 2 issues. This could be due to his being able to concentrate on just that his writing. The art duties have been handled by Guillem March. I haven't following his work on Sirens and was ok with his work last issue on my first read through. However, the second time thru I liked it much more. He has a kinetic style that really lent much to the story. This is again true this issue and in fact there isn't a panel that I don't like!
The riddle of last issue is explained and we are left with a bit of a cliffhanger that will have to hold over for the 3 months. Dick got to show his skills as a detective and he really shines. At times it may have felt a bit Bruce like but I think that is more just Dick filling out the role more than anything.
This issue is a complete package both writing and art! I again strongly recommend this issue and if Daniel is still writing after the Grant Morrison interlude then his continued run on the Batman series!
