Tree hears a gunshot and her father runs down the stairs and out the door. He tells her to stay behind and wait for him to return. Tree's dad is the town doctor, and he is going to see if someone needs his help. Tree, of course, follows along and witnesses a scene that she does not quite understand. She begins investigating so that she can write a newspaper article about what really happened. However, when she spends more time with the person who she is pretty sure is the guilty party, she is not quite sure what to do with the truth.

Some secrets are best left uncovered while some secrets have to be shared. Join Tree as she finds out when to tell the whole truth and when to keep it to herself.
