The Obsession

This is like the junior version of “Gone Girl”. Both Logan and Delilah are a bit unhinged.

I'm not sure if it was meant to be predictable, but it was obvious from very early on that Delilah is part of the drug dealing shenanigans at Draycott.

Loose plot thread: whatever happened to the neighbour's garage camera footage? What was the point of Mendez poking around?

Sutanto gets around any potential plot holes by ending the book before any repercussions can play out, but if we (the readers) had been able to stick around a while longer, I think the whole story would have unravelled.
