Mildred A. Wirt was an American author. She is best known for her work on the early Nancy Drew series.
Penny Parker starred in a series of 17 books written by Mildred A. Wirt Benson and published from 1939 through 1947. Penny was a high school sleuth who also occasionally moonlighted as a reporter for her father's newspaper. Benson favored Penny Parker over all the other books she wrote, including Nancy Drew. Her obituary quoted her as saying, "I always thought Penny Parker was a better Nancy Drew than Nancy is," Mrs. Benson said in 1993.

A sporting goods store offers a prize of a complete archery set for the organization that puts on the best play. Den 1 and Den 2 plan to put on a play as a joint effort in hopes of winning the prize. The Cubs decide to put on a production of Robin Hood and receive permission from Mr. Kain, who works for the bank, to use a property known as the Haunted Castle as the setting for their production. All appears to be going well until the Cubs are accused by Mr. Kain of breaking a window and setting a fire. Mr. Kain orders them to pay for damages or leave the property. The Cubs have seen someone hiding in the bushes on the property, but since they have no proof, they pay Mr. Kain so that they may continue to work on the play. As the Cubs finish working on their play, they investigate the bank's property, hoping to meet the trespasser and prove their innocence of any wrongdoing. In time, the Cubs learn the identity of the trespasser and exonerate themselves. Additionally, they help a new friend become a Cub Scout.
The Cubs of Den 2 face their biggest crisis after they are accused of vandalizing an old church. Dan admits that he and another Cub are responsible for accidentally breaking a window and offers to pay for the damage, but the caretaker, Old Terry, refuses to accept the money and states that they did thousands of dollars in damage to the building in addition to breaking the window. Dan and the other Cubs are angered, as they know they did not wreck the church. The owners of the church file a lawsuit against the organization for $20,000 in damages. Even worse, the boys' reputation is at stake as many people believe the false rumors. The Cubs feel disgraced and have no way of proving their innocence. The Cubs suspect that hooligan Pat Oswald and his gang are responsible for the damage to the church. Pat and his cohorts constantly harass the Cubs and make fun of them. Whenever the vandalism of the church is mentioned, Pat smirks but refuses to admit to anything. Finally, Pat has a change of heart and admits to his role in the misdeed. Pat and his friends resolve to become honest and loyal. They plan to create a Cub Scouts den of their own so that they can also be members of a great organization.
