Red Dead Redemption

Right this is getting on my wick. Ive been Jack for quite a while now & done a good few missions with him. The Mexican hooker is dead & ive cleared so may places of bandits & ne'er do wells that im getting fed up. Does a prompt appear to tell you where to go to finish this or what? I dont want to be riding round the whole lands over & over. This has been well over an hour at this stage. Ive also sorted the english guy out with the opium etc etc.

As Jack, ride into Blackwater and hit the train station, there is a federal agent there. If I remember right, he will have the stranger icon above his head. He'll tell ya where to head next.

It's not a long quest, he'll direct you to a small 'vacation house' southeast of Armadillo, where that person will give you the location of the final confrontation along the river in Mexico. After that, listen to the song. It's a nifty one (I think, anyway).
