Detailed walkthrough
As you approach Rook House in Salem, you can see a man standing on the roof of a house, which is surrounded by mirelurks. The lurks will attack you. After they are defeated, get closer and Barney Rook will speak to you and invite you to enter the compound. Go to the basement- Barney will not speak while on the roof.

If Barney Rook is dead when you first approach, as frequently seems to be the case: Prior to killing the mirelurks, you can enter in console:

~prid ff000ce4 (or ff000af3, this seems to vary)

hit enter and then write

~recycleactor ff000ce4 (or ff000af3)

If you already killed the mirelurks, go to his body (you may need to jump the fence), go into console, select the body. The id given above should appear. Then type:

~resurrect and then:

~setstage DN083_Barney 15

Barney will speak to you, continuing the quest.
