Whatchamacallit, Thingamajig

Abby had her fingers full of chocolate cookie dough. She was putting her fingers to her mouth to sample a taste while no one was looking. Maggie had her back turned to Abby. She was sneaking a couple of chocolate chips out of the bag and into her mouth before she gave the bag to Abby so the chocolate chips could be added to the cookies. Both of them had their hands halfway to their mouth when the phone rang. Both Abby and Maggie jumped and quickly dropped their hands to their sides as Brady ran into the kitchen and snatched up the phone. *Brady, Brady, all of you have to come quickly. I need your help.* screamed Grandma. Yes Grandma is in trouble again and the four cousins scramble to her aid. What they find when they look for her is a ransacked house, a missing Grandma and clues they don't understand. What they learn about Grandma leaves them wide eyed and open mouthed.
