The Case of the Vanishing Field Trip Money
The Anna & Ava Detective Agency (Book 4)
The envelope was there yesterday.
Today, it's empty.
The field trip fundraiser has been collecting money for weeks. Bills folded carefully. Coins dropped in with loud clinks. Every dollar counted.
Until it disappears.
Whispers move faster than facts.
Eyes start to narrow.
And suddenly, someone is being watched.
AnnaBelle doesn't like messy numbers. Money is supposed to add up. If it doesn't, there's a reason.
Her younger sister Ava notices something else.
The student everyone suspects doesn't look sneaky.
They look worried.
As the sisters open their fourth official case, they discover this mystery isn't just about missing cash. It's about trust. About assumptions. About how quickly people decide what must be true.
And sometimes the real problem isn't what vanished.
It's how fast blame appears.
Warm, thoughtful, and grounded in real-life school moments, The Case of the Vanishing Field Trip Money is a heartfelt chapter book mystery for readers ages 7-12 who love:
- School-based mysteries
- Detective stories about fairness and trust
- Realistic sibling dynamics
- Stories about courage and accountability
- Mysteries where solving means understanding
This isn't a story about catching a thief.
It's a story about looking closer - before you decide.
The Anna & Ava Detective Agency is officially open.
