I just had the messenger give me the letter telling me to meet Dekaras in the docks. I slept for 24 hours and then scoured the Docks. I couldn't find Dekaras anywhere. Could somebody please tell me where in the Docks I am supposed to meet him?

EDIT: I loaded a previous save to before I was contacted to meet Dekaras. The problem appears to be that I was in the Docks district when the messenger arrived. The errand boy never spawned. In my replay I was in the Slums when the messenger contacted Edwin. Then when I went to the Docks the boy spawned as normal and I am once again proceeding with my game.
