Mystery at the Softball Nationals (Book 13). Ava & Carol Detective Agency: A Kids Sports Detective Mystery (en Inglés) - Thomas Lockhaven;Grace Lockhaven

When the coach of a top-ranked softball team contacts Ava and Carol Detective Agency, she's desperate. She's convinced the rival team somehow knows every pitch before it's thrown. The problem? There's no proof-just a growing suspicion that someone is secretly feeding signals to the batter.

To uncover the truth, Ava and Carol go undercover.

Disguised and working as assistants, the girls join the team to investigate from the inside. But the deeper they dig, the messier things get. Is the cheating coming from the rival team... or from someone on their own bench?

With the New England Softball Nationals on the line, college scouts in the stands, and scholarships hanging in the balance, the pressure has never been higher.

Soon everyone becomes a suspect.

With help from their friend Derik watching the crowd for hidden signals, Ava and Carol race to uncover the truth before the final pitch is thrown. Because once the championship game ends, the damage will be done.

And if they pick the wrong suspect... they could lose far more than the game.

Perfect for readers who love the mysteries of Nancy Drew, The Boxcar Children, Encyclopedia Brown, and A to Z Mysteries, with the added excitement of championship softball.
