Marjorie Weinman Sharmat and her husband, Mitchell Sharmat, have also coauthored many books, including titles in both the Nate the Great and the Olivia Sharp series.
Rosalind Weinman, a portrait artist, lives in Tucson, Arizona. Her recollection of a mysterious middle-of-the-night phone call that woke her father, Nathan (the original Nate the Great), and mother, Anna, inspired this book. Rosalind Weinman has shown exceptional bravery in allowing the character Rosamond to be named after her.
