A Scanner Darkly — Philip K. Dick

ONE CAN LIVE AS DANGEROUSLY AS TWO IN THE MOST OUTRAGEOUS AND SPACED-OUT NOVEL IN YEARS!

WHO'S WHO?
Fred, the unstoppable undercover narc in a scramble suit that gave him virtual anonymity, was out to bust doper, pusher Robert Arctor. A snap for Fred, except for one small catch... he was Robert Arctor!

WHO'S WHAT?
Now Donna was Robert Arctor's girl, as well as his dealer, and a pretty important broad in his life. But she was just the sort of female who was important in a lot of guys' lives...even a guy who was a narc like Fred!

WHO'S WHERE?
But once Fred was assigned to get the goods on his other half, his whole world came apart. Not only wasn't he sure how to play the government's game, he wasn't even sure which side he was on...or which side he was going to let win!
