"Nancy Drew" The Mark of the Poisoner’s Pearl (TV Episode 2020)

Synopsis

Storyline:
After discovering a connection between the poison that killed Tiffany Hudson and a Horseshoe Bay cold case, Nancy and her friends risk their lives to bring a serial killer to justice.
User Reviews: If Ace’s dad lost his hearing, on the job, as an older adult, why does he act and speak as someone who’s been deaf most or all their life? Makes no sense. They cast a deaf actor and then tweak the story to make it fit? Except…it doesn’t.

Better mystery story for this one, but still misses the mark.
