"I see we'll have to do it the hard way," Ellery said. "Sorry I can't produce the thief with a flick of my wrist, the way it's done in books, but in real life, detection — like crime — is pretty unexciting stuff. We'll begin with a body search. It's voluntary, by the way. Anybody rather not chance a search? Raise your hand." Not a muscle moved.

Which sentence from the excerpt adds the most suspense?

Not a muscle moved

Explanation:

The introductory sentence I see we'll have to do it the hard way shows that Ellery is in front of a group not very willing to cooperate. When he/she asks the trick question Anybody rather not chance a (body) search, making a raised hand a possible suspect, nobody makes a move. This leaves the detective without any clue yet to possible suspects.

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
