It's a Loud family whodunit as Lincoln Loud is looking for his stolen lucky drawers. He suspects one of his ten sisters (either Lori, Leni, Luna, Lynn, Luan, Lucy, Lola, Lana, Lisa, or Lily) could be the sticky-fingered culprit! Then, Lola takes on caring for animals as Lana comes down with a case of food poisoning and is too sick to watch her many, many pets. Will she roll up her gloves and take on this dirty job? Meanwhile, Lincoln's friend Zach hunts a monster at the school. All this and the Casagrandes too! Is Sergio able to level up in the Casagrandes household? Available in softcover and hardcover editions.
