"We've always been fans of a good mystery; we think all kids are, and there weren't any good mysteries out there these days for kids, so that's why we decided to do them"

In this quote, Mary-Kate Olsen catches the intrinsic appeal of secret stories and their universal attraction for children. She and her sibling Ashley, recognizing this fondness, sought to fill a perceived void in kids's literature or media by producing mysteries tailored particularly for young audiences.

The expression "We've always been fans of an excellent mystery" hints at Olsen's personal interest and long-standing gratitude for the category. This recommends a deep understanding and connection with the aspects that make mysteries fascinating, such as thriller, intrigue, and the intellectual challenge of piecing together clues. By stating "we think all kids are", Olsen suggests a basic belief that kids have a natural curiosity and love for expedition and analytical. This curiosity is essential in the advancement of vital thinking and cognitive skills, which mysteries can assist to support.

Furthermore, Olsen observes, "there weren't any excellent mysteries out there nowadays for kids", showing a gap in the market. Regardless of the historic success of children's mystery tales like those of Nancy Drew or The Hardy Boys, Olsen seems to suggest that modern offerings at the time lacked in quality or amount. This viewed shortage could have been because of shifts in home entertainment trends or perhaps a failure to upgrade conventional formulas for modern audiences.

In response to this space, Olsen and her collaborators decided to develop new secrets specifically for children. This choice shows an entrepreneurial spirit and a proactive technique to providing improving material that resonates with young readers. By establishing secrets, they aimed to engage kids in narratives that challenge their creativities and reasoning abilities, while also amusing them.

In essence, this quote shows Mary-Kate Olsen's devotion to producing meaningful, interesting material for kids, driven by a shared passion for secrets and a desire to contribute positively to a child's intellectual and creative development.
