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.

Carol responds:
I don't think James, Lily, or Sirius *could* have told him because the
Secret Keeper's identity was part of the secret itself, which could
only be revealed by the Secret Keeper. And Peter, of course, had
reasons of his own for not revealing the change.

Carol, who agrees with Pippin's interpretation of McGonagall's words
(DD either suspected Sirius or could not rule him out as a suspect)
