It’s spring break, and Max and Chad are thrilled to be in North Platte to visit Carly and Molly for a whole week! Carly can’t wait to introduce her cousins to her friend, Kate. Fun, here we come! But, before the fun hardly starts, Aunt Susie and Carly volunteer the whole group to clean out Kate’s great-grandma’s apartment? Her PINK apartment? Bye-bye fun. This is the Double Cousins we’re talking about, though, and as usual, they manage to turn it all into an adventure and a mystery. Buffalo Bill himself gave Kate’s Pawnee ancestor a very special wedding present—a necklace that came from the Grand Duke Alexis of Russia. But where is it? And Earl, Slim’s old buddy from his train jumping days, sure seems like a nice guy, but will he tempt Slim to go back to that old life? And what about Shelly, Kate’s cousin? There’s something not quite right there, either. When some money goes missing, they ALL fall under suspicion. Can they find the Russian Jewels, finish the job they’ve started at Gigi Pinky’s, and figure out who the real thief is before it all blows up in their faces? Come join the hijinks and make some new friends along with Max, Carly, Molly, and Chad.
