Query: NOT what it used to be

Was there even a mystery in this book? The last three I've found Ms. Brown losing her mind and senility and especially her writing finesse. All that was talked about was practically a few days in Qwill's life and mindless drivel you might read in a newspaper. As soon as Koko acted strangly, that was it; mystery over in chapter 4. It was a 2 hour read, no miss on solving the mystery myself, and tragidies that were completely unnecessary. I'm just going to imagine my own next few stories to make myself happier because this and the other last two were wastes of my time/money.
