Just Watched Black Butler: Book of Murder.
Overall I found this great. 9/10 You have the mystery of the murders in the mansion.
First was Georg von Siemens and at first glanced he gets killed in a locked room. So you think how could anyone realistically kill him. Well nobody did and he faked his own death. But ironically he was a target for the Queen, which led Charles Grey to kill him. It does bring me curiosity whom the Queen really is behind that mask? And how similar it is to her S1 filler counterpart.
Second was Patrick Phelps, and he was a more tragic case. He simply is a causality of the circus arc and snake. Simply put he was killed because he slept in Ciel's bed. Now Snake is right that Ciel and Sebastian were responsible for his mates demise. But it seems he was not involved in the kidnapping unlike the others surprisingly. Though it is quite cruel that Ciel lied about the fate of his friends.
Third was Sebastian and this is where the OVA got too fancy for its own good. It's unbelievable that Sebastian this early in the series would die. Now the most interesting thing is that Charles Grey intended to get rid of him. Now the decision to kill the victimized children in the fire rather than returning them to safety despite being traumatized seems to be a sticking point between the Queen and Ciel. Letting the children die is cruel to the queen. But isn't it more cruel to let those traumatized children to live. Ciel knowing they won't have a Sebastian to aid them. I would side Ciel made the right call.
Although dead ass Sebastian swapping between him and Jeremy seamlessly and able to hide his footsteps had me
. I do feel bad for Arthur, he was a genuine good dude, that got caught up in a big act. The goal for Ciel was to simply be in the Queen's good graces and not catch the actual murder. Charles Gray serves the Queen and that would be an impossible task. His argument that detaining Carl Woodley is justified because he is responsible for other crimes. This shows once again Ciel and Sebastian while the protagonists, are not good guys.
Next planning to watch Book of Atlantic
