Miss Dunn is the organist on the WFIDO radio soap opera It's a Dog's Life, as seen in the first season Dog City episode "Radio Daze." She provides the dramatic stings, musical transitions, opening fanfare, and all other music for the series.
The quiet, composed Miss Dunn is fingered by Spot as the most likely culprit behind the rash of violent "accidents." Even Ace Hart suggests it's her, hiding behind the safety of her organ. The loosened floorboards beneath her immediately collapse, however, proving that it was not Dunn who done it, but was nearly done in instead.
