The Light in the Cellar: A Molly Mystery (American Girl Mysteries)

Molly wishes she and her friend Emily had an exciting volunteer job that really helped in the fight to win World War Two. Instead, they're magazine delivery girls at Oak Knoll Hospital. Soon, however, Molly and Emily start to suspect that something very un-patriotic is going on at Oak Knoll--and their snooping leads them deep into trouble!
