lure out the culprit

Exploration Stage: Hat Salon
From: Anna Weber
Description: It is now clear that it was not me who poked a hole in the hat and it was not Mr. Delamode who ruined the pattern. In other words, someone is plotting to put us at odds. But who? Help me make a dummy glove to lure out the culprit.
Completed: Thank you very much. Let's catch the culprit red-handed, aiming at the time when he tries to work on these gloves. I hope that solves the problem...because the fashion show is coming up and we don't have time to rework the piece.
