Dog Lover

From: Augustine Capuchin
Description: Ms. Woodville invited me to film the solving of an old case for the archives, and she’s letting me help! Of course, I signed non-disclosure papers. There’s a note in the file that Winters’ best friend was a dog lover. Maybe he had an ultrasonic whistle? Let’s find it!
Completed: You found the ultrasonic whistle that John Winters’ friend used to train his terriers. Do you think he envied Winters’ wealth and wished him dead? I hope the whistle will help us shed some light on the mystery of such a puzzling murder!
