The Dock Captain just sent word that he spotted Sokolov. Knows his habits. Says Sokolov buys whale blood off the boats by the gallon, to make pigments apparently.
See, you seem to share some interests with the old genius, so why don't you go and invite him over like we said? The sooner the better.
He's probably staying on a boat in the bay, I trust you'll be able to follow his scent. Keep him safe in Addermire. Don't hurt him, or he will be useless for our plans.
If you're hungry though, the Dock Captain has served his purpose, and his second in command recently did me a favor.
