Well dishonored again I'd say. First your going to have to get back to the hound pits pub exactly.
Follow markers, until you eventually get to piero's. Go in To his shop and except his quest. He will then give you items, as well as disable all of the guards in the mission.
When you are looking for havelock, head to the bar it is just a note.
Important there will be NO marker for the smoke signal. It Is in emily's tower though, where the audiograph player is. Right near the window is the flare switch. remember NO marker.
Then head to Samuel again for a ride to mission 9 the last part of the game.
