Then all you have to do is wait for McBane to walk around inspecting his half-built house, interacting with the shoddy wall, and he'll fall and crush it. Once you've taken out a good number of the gunmen in the area, you should be able to kill the poncho man in the half-built house without anyone noticing. You will have to eliminate a large number of the armed men around him in order to climb into the house under construction (and visible in the image above). Contacting him is not too difficult, although it does take time. McBane hangs out around the construction site on the right side of the map. Once you get the poison, go back down to the room with the whiskey cask, poison the cask, then exit from there. You don't have to worry about the bartender going around on a loop because she won't trigger an alarm when she sees you. Follow the patterns of the enemies in the house and kill all the gunmen you need as you sneak up to the second floor to catch the poison. A poison bottle is located inside the brothel, on a table towards the back of the second floor (in the photo above, where you see the smoke in the lower right corner of the brothel). You can poison the whiskey cask, but you will need to get poison first. Again, pick up all the gunmen you need and head to the back-outside of the brothel until you reach the entrance to the room with some whiskey casks (in the upper left corner of the image above). There are several ways to enter, but we have found the easiest to get around the west side, through the post office. To get to Wild Marge, you'll want to go up the map from where you killed Jarvis and to the brothel. Anyone who sees him will be worried for a few seconds, but he will not be alarmed and will soon resume his day. The cow goes gouge Jarvis to a quick (but painful) death. Once you're close enough to Jarvis and his pasture, wait for him to go say hello to his cow, then flip a coin at the animal. To get closer to him, you just have to go up from the bottom of the map and methodically eliminate all the enemies you see so as not to get caught. You can attack your targets in any order, but Jarvis is the closest and arguably the easiest. Remove the four with "crashes" and you will also receive one of the badges from this mission. You can remove your targets as you see fit, but there are some nifty tips you can use for each of them. These could be the four targets you need to assassinate, but we're willing to bet that the troublemakers are actually Cooper and Hector themselves. In Desperados III's third mission "Troublemakers in Flagstaff", you never know exactly who the troublemakers are.
