Locate the black market shop (optional) | Mission 2 Dishonored 2 Guide

There's a rune inside the dead whale's mouth.

Your first optional objective will be to find a black market shop. You are currently inside a neutral territory - there are no guards here who could attack your character, so take your time and freely explore the area. On your way to the shop, stop by the dead whale in the docks (on your left), there's a rune in its mouth (use the heart if you need an exact location). Before you go there, though, collect the map that is hanging in the central part of the location. After you pick up the rune, collect whale oil (10 coins) and raw whalebone from the table nearby, then board the boat tied to the pier near the whale carcass. Inside, you will find Audiograph: Miner Recruitment, Whaling Territories loot item (50 coins), and 20 coins under the bunk.

The entrance to the black market shop is marked with a special icon showing a pair of hands.

The entrance to the shop is marked with a pair of hands (see screenshot). Move through the corridors following the trail marked by hands and you'll get where you need to.

Talk to Mindy to accept optional missions.

On the way, you will hear a woman talking to you from behind a window. Listen to her, as she'll have some optional tasks, which may help you in achieving the main objective of the second mission. The shop itself offers upgrades, ammunition, treasure map and a rune; but if you'd like to save your coin, you can steal from the fence using a clever trick (you'll find detailed information in the Special actions section, under "Black Market Heist")
