The New Avengers?

In the final contest for ARCs of The Shanghai Moon, SJ Rozan asked, if Bill Smith and Lydia Chin were invited to a Halloween party, what would they go as?

I answered:

I'll take a wild stab and say Lydia goes as Emma Peel. It's not how I see her or how she sees herself, but the fun of Halloween is letting your imagination run (within reason).

And I think Bill would deduce Lydia's choice of catsuit and go with the bowler and cane (sword optional) of John Steed.

UPDATE (4:30 PM): I won!
