Kathy Young and Latchkey Mystery by Margaret Goff Clark

In Who Stole Kathy Young?, Meg is walking down the road when she sees her best friend, Kathy, abducted right in front of her!  Meg is horrified and runs to Kathy's house to tell her father.

Meg is worried about Kathy, who is deaf.  The van used for the abduction is recovered, and Meg finds the power pack for Kathy's hearing aid inside the van.  Kathy can hear nothing, rendering her helpless.  With few clues, Meg and her friend, Julian, ask a private investigator to help them find Kathy.

It was fun trying to guess the culprit as I read this book.

The story is very good to excellent.

In The Latchkey Mystery, burglars are breaking into houses in Minda's neighborhood.  Minda forms a neighborhood watch group with her school friends who live in the same neighborhood.  They call themselves the Ferrets.

The Ferrets devise various methods to keep an eye on the neighborhood.  Each Ferret keeps a list of suspects and writes down anything suspicious that they see.

This is a very good book.
