There were definitely a few more balls up in the air than are easy to keep track of. The locked-in-the-tool shed thing made me go Huh? Because then I'm like, Okay, when, and by whom, and why? How does that affect the backstory? In the present, does he have to get locked up for the ghost to be able to come in and be the babysitter? But that seemed unnecessary to me, since I just assumed that he would send the ghost/babysitter. But maybe not?

And that's two types of locked-up, because we also have the ghost daughter being locked up in the attic, and when you have two of something, you start looking for similarities, and I couldn't quite find them. I could see that the crazy poet might lock his daughter up so she wouldn't bother him while he was doing his black magic.... or maybe he had other sinister ideas in mind? But I just keep coming back to wondering why Groundskeeper Willie, there, needed to be locked up.
