Hello! It's been a while but since the whole series is now translated in French, I restarted the series from the start and I'm near the end of the Bonehunters. There's something I don't understand, spoilers ahead, I don't see the spoilers tag.
I'm at the scene where Tavore got in front of Laseen. How the Chain of Dogs was lied upon? I don't understand how Kobolo and Mallick twisted the reality so that Laseen think the Wickians (typo?) are responsible of Coltaine's death? I think I had the same difficulty when I was reading in English and it's not different in French, it's like I missed a part where those two return to Laseen to propagate lies?
Out of spoilers, I'm really happy that Leha editions translated the whole series, I was missing some good information with the original version, even if some of the books I've read fourth times! But that time, I'm reading them all non-stop!
Thanks!
