"He suspected Black?" gasped Madame Rosmerta.

"He was sure that somebody close to the Potters had been 
keeping You-Know-Who informed of their movements,"said 
Professor McGonagall darkly. "Indeed he had suspected for 
some time that someone on our side had turned traitor and was 
passing a lot of information to You-Know-Who."

"I gather from this that Dumbledore was already trying to find out 
who the traitor was and had been unable to eliminate Sirius from 
his list of suspects."

DuffyPoo:
I've thought that was a very good non-answer on McGonagall's part, possibly to the point that DD hadn't suspected Sirius until after the blowing up of Pettigrew incident.  As has been said before, everyone suspected everyone else.  The original Order members were being picked off one by one, at that time, yet the spy remained.  Everyone was a suspect.  Except, of course, Peter Pettigrew.  DD knew he himself wasn't the spy so the spy had to be someone else.  Sirius knew he wasn't the spy so the spy had to be someone else.  Etc, etc.  DD apparently didn't know about the S-K switch or he wouldn't have given testimony that Sirius was the Potters' S-K.  Did James/Lily/Sirius/others suspect DD and so he wasn't in on the switch?  It was made nearly a week before the attack, after all, plenty of time to tell him.
