Pluto vol 2 by Naoko Urasawa and Takahashi Nagasaki

Based on Astro Boy by Osamu Tezuka

Geischt chats with one of the other seven deadliest robots, a young boy robot name Atom. Geischt is there to warn him about the deadly attacks and murders, but Atom thinks he can help the investigation. He asks Geischt for his memory chip and becomes entangled in the investigation of the murder of Dr. Junichiro Tasaki, a professor of law who was instrumental in writing and passing the Robot Laws. Atom discovers that, in his final moments, Dr. Tasaki was trying to contact Professor Ochanomizu, a man who was on the Survey team into Persia with Dr. Tasaki before the war broke out. The group was tasked with finding the deadly Persian robot army, but found nothing, and its remaining members also seem to be targets as well as the deadly robots.

---

The mystery of the robot and human murders continues and is deepening with the inclusion of the other deadly robots. This volume also includes a look back at the history and the war that made them all famous, and the robots sharing their various perspectives that enhance the history. There are some major hints in this volume as to who the murderer is, but there's also still plenty left hanging to keep readers going into the next volume. 

This series is a little bit slow-building, so it may only have readership where Urasawa's other works are popular, or where readers already know and love Astro Boy.
