"When a neighbor calls about ghostly noises in her attic, Kaz and Claire agree to investigate. Could that very familiar-looking ghost dog Kaz sees through the attic window be his lost dog, Cosmo? Venturing outside could be dangerous, but Kaz has to find a way to be reunited with Cosmo before he loses him for good."-- Kaz, who is an ordinary ghost, and Claire investigate a noise in an attic that might be Kaz's ghost dog, Cosmo.
