"Don't call me elderly!"

Gertrude is still feeling confident after her first gumshoe victory. So when she finds a murder victim at her local thrift store, she is excited to tell the Sheriff's Department everything she's learned at the scene of the crime.

Unsurprisingly, they don't listen. So Gertrude must solve the mystery herself. And the only way she can figure to do this is to go undercover—as the Mattawooptock Thrifty-Help's newest team member. Anyone who knows Gertrude knows this probably isn't the best idea. She'll probably get fired. Or arrested.

Or worse.
