The Beginning of the End

While reading chapters 5 through 11, it seemed to me that Burke and Hare were even less careful than when they started the murders.  People noticed them carrying corpses on the street, a body was recognized when they sold it to Knox, one of their victims was a relative of Burke's wife, and Hare even committed a murder alone.  These things signaled the beginning of the end to me.  I was also really surprised to see that they had help from their wives with at least one of the murders.
