suspicious purchase

[Innominatus 0]

hello. 

I got a problem with a quest "Suspicious purchasing". I can't find an NPC named Sott - he doesn't appear. Please, help me with it.

That looks like the Suspicious Errand quest to open Kromede's Trial.In that quest your next npc to talk to is Kehleb,who is in Pandaemonium,in front of shadow court.
