The sudden and unexpected arrival of a mysterious package interrupts would-be private investigator Hat Tintersmoot’s twelfth birthday. Once she discovers that the small cardboard box is a present from her Grandpa Gordon, the mystery deepens . . . considering the fact that he passed away three years earlier.

It's another perfect job for the owner of The Marshmallow Hammer Detective Agency. With the help of a new friend with a troubled past, Hat must solve five nearly impossible clues in order to uncover the baffling truth behind a gift from beyond the grave.

"This is an above average middle grade solve-the-riddles/scavenger-hunt adventure with an engaging heroine and a light, observant and insightful touch." --Amazon Top 500 Reviewer
