Okay, yes, this is silly - the mystery is silly, the resolution is silly. It's all silly. Zoe is ridiculous. Digby is a jerk. 
 I kind of like this anyway. There's no part of me that could take this seriously. There's no part of this that should be taken seriously. In truth, Zoe's pretty light on personality. And Digby really is a bit of a jerk (to normal people!). Parts of his personality resonated with me because I am also cursed with a lack of awareness as to how my words will, at times, come out and how they'll be taken. Unlike Digby though, I've realized I have a deficiency in that area and try to pay more attention (I'm still, at times, totally unsuccessful.) 
 I do want to know why Digby wears a suit. Why? Why?
