Burke and Hare-Chapters 5-11

Up until now it seems that Burke and Hare were doing a decent job of concealing their murders by disposing of the body during the night, and murdering only those people who weren't well known in town. However, in chapters 5-11, they murdered the two people that, if gone missing, someone would notice--Mary Patterson and Daft Jamie Wilson. Because of this, and carrying Mary's body through town during daytime hours, it seems that Burke and Hare's plan to make easy money is failing. Not only that, but they are failing as a team, killing people behind the other's back, creating tension between the two partners and arguing right before the last murder. It's also interesting to note, that Burke barely got away with the Patterson murder as the friend she came with left her with Burke after the argument with his wife. And the next day, as they were carrying the body through town, multiple people saw the bag containing her corpse. If the friend went looking for Patterson, it should have been easy to implicate Burke and Hare with the murder. However, it seems they barely get away with it.
