Ever feel like something suspicious is going on? Eleven-year-old Jake sure does! He just knows his cousins Max and Alexandra are trying to steal his grandfather Peter's rare baseball card collection. Now, Jake is on a topsy-turvy mission to prove it. The problem is that his grandfather has lost his memory to Alzheimer's and, unless his new drug trial somehow miraculously helps, it's not coming back. So what's a boy to do, especially when his parents don't believe him? Turn to his lovably strange friends - genius Brit, mischief maker Rowdy and computer whiz Noah - to help solve this crime before it's too late! ¿A portion of proceeds from this book will benefit the Alzheimer's Foundation of America.
