What would you do if you got a letter like this?
Grady Jones has never been Great at anything, but when he gets this letter, he decides that maybe that means he'll be a Great Detective!
The only problem is, for a Great Detective, he lacks some basic skills, such as solving puzzles, interviewing suspects, or collecting clues.
Fortunately, his neighbor Mikayla Morales is good at all those things, and between the two of them, they just might solve this thing. Until a mysterious stranger shows up, and changes everything they thought they knew about the case.
