Sheila Altoonian unmasked

Sheila unmasked.

Although Sheila was supposed to be one of Nan Blake's friends and was about the same age, she was secretly jealous that her friend still looked young and beautiful while her looks were starting to fade. Aging gracefully not being an option, she dressed up as a vampire to steal things for her youth potion. This led to suspicion by Mystery Inc. and Sheriff Bronson Stone that Nan might be the vampire. When it came to the climax at a local museum, they trapped the vampire. When Daphne Blake was about to stake it, the vampire gave up, revealing herself to be Sheila who wanted the stolen items to create a youth potion to regain her beauty. Sheila was eventually arrested by Sheriff Stone.[1]



  • Sheila is one of the very few culprits to unmask themselves.
