zgirnius:
I vote for Peter Pettigrew as the Muggle-born Death Eater. His 
friendship with the Potters, in whom Voldemort had such a great 
interest, could qualify as an unusual circumstance. And it answers a 
couple of questions for me.

Why did Sirius and Lupin suspect each other of being the traitor?
Well, if Peter was Muggle-born, both might reasonably have figured that 
Peter was not going to be recruited by Voldemort for ideological 
reasons. (Whereas Sirius, as a pureblood and a Black would be eminently 
acceptable, and Lupin, while a half-blood, is also a werewolf...) Also 
another reason why Sirius and the Potters mught have considered the 
Secret-Keeper Switch an extra clever idea.

How did Peter kill all those Muggles?
Well, the Muggle authorities passed the whole thinkg off as a gas main 
explosion. Perhaps is really was. Peter as a Muggleborn would know 
about such things and may have set the explosion off magically to hide 
his escape.

It also rounds out the Marauders nicely. The three whose blood-status 
we know of fir sure are a half-blood and two pure-bloods. It might also 
help to explain why Peter was such a suck-up. This may have been his 
strategy to deal with the Wizarding World, once he realized that not 
all would welcome 'his kind'.
