You are cordially invited to a members-only Minerva Keen's Detective Club Party at Treehouse on Wednesday, August 2 from 6 p.m. to 8 p.m. The amazing author of the new “The Minerva Keen's Detective Club,” Keir Graff, will be here in person to talk about this book and his other popular young reader novels at 6:30 p.m. in the Storybook Theater. Then, we’ll solve a mystery together, figuring out coded clues and using deductive reasoning as we interview our cast of characters throughout the Museum. Make and keep your own “decoder rings” and enjoy the prizes and surprises planned for the whole family. Best for children ages 6 and up.
