Yes there's also one chapter where they actually had proof when the pope knew the eye color of the dragon (Melmont and Abel did not mention any of it so they figured it was them who was behind their master's death because besides the two of them, only their master knows the eye color of the dragon in the dream)
The master of abel is def assassinated it was foreshadowed using the shadow and the cow(?) or something. I don't really remember but there is a shdow showing of someone and the door knocking. And the pet thing being left behind. I thought this is pretty ovb, but well
I was rereading cuz I frgt some plot... On chapter 6 i realised.....maybe the master of Abel was killed. Duke trude tells melman that he will be sure to pay his master a visit.......in chapter 5 when Abel and melman come back from palace. Melman notices the misplaced stuff and thinks someone robbed them...then they find master dead.. plus the master earlier mentions that melman didn't tell about the black liquid from the dream.if melman didn't mention, the Duke would have called the master... I think the master knew what was gonna happen to him.. duke killed him bez of the black potion that Abel mentioned from his master s dream......but it's just sad that the master died..poor Abel he even got some palace good for his master...
