I didn't know he had died to be honest i thought he had just returned to the GQ, which book is that in?
No book as of yet, that's the problem. It's been hinted in the last few novels by DRGIII that something happened in the 4 years between The Soul Key and RBoE that involved the Even Odds
and this character we speak off. Appereantly, this character died then. We don't know any of the specifics, only that it happened.
