Three girls and two boys who live in Tenth Street have formed the Tenth Street Reading Circle. They read detective mystery stories together. One day, Betty Bliss suggests forming a detective club. They will call themselves Tenth Street Yard, after the London Scotland Yard, and Betty will be Superintendent.
At first, the two boys do not think girls can do good detecting, so they laugh at them and refuse to join the club. But after they have solved several cases successfully, the boys begin to admire the girls and want to join the club. After that, they succeed in solving a number of cases.
The original stories are written by Ellis Parker Butler (1869-1937), famous American humorist, author of more than 30 books and more than 2,000 stories and essays.
