Wine Stopper Line Up

Email received this morning:

 

"Dear Brina and Davy,

 

Sorry to hear your wine stopper has escaped. We're not exactly sure

what happened to it. In an effort to apprehend the fugitive, we have

rounded up the usual suspects here at the Treehouse. We're liking the

fourth guy from the left for your job. Can you ID him?

 

Mark and Lois"
