They could make a movie out of this.
And then someone steals the sketchbook. So, your dad goes after them.
"I don’t know who you are. I don’t know what you want. If you are looking for ransom I can tell you I don’t have money, but what I do have are a very particular set of skills. Skills I have acquired over a very long career. Skills that make me a nightmare for people like you. If you let my daughter's sketchbook go now that’ll be the end of it. I will not look for you, I will not pursue you, but if you don’t, I will look for you, I will find you and I will kill you.”
So your dad goes to look for the sketchbook thief. And it's assumed he gets killed.
And so the police get called, and then you see onscreen 200 cops surrounding a building, and a 20 minute action shootout scene. Where every cop gets killed 1 by 1. Until it's just the theif, and you, and your daughter. In a big dark warehouse with creepy overhead flickering lights.
Then your dad, who's not been onscreen in 45 minutes, assumed to be dead, makes a late movie comeback where he does a backflip, snaps the bad guys neck, and saves the day.
Final shot of the movie is your daughter happily sketching at home. Then the camera pans the sketch, as it shows 200 cops all in a bloody warehouse, with you, your daughter, and your dad, all shooting the cops. As the theif looks on in horror in the background.
Implying the whole movie, was just a simpleton theif, stealing what he thought was an unimportant item. Something that wouldn't cause too much trouble.
........but then a family of psychopaths used it as an excuse to kill 200 cops, and frame the theif.
And they would have gotten away with it too, if it weren't for that meddling exposition of the story at the end!!!
