Query: Why do I keep buying Susan Hill's mysteries after reading this book?

I could tell by the pages left in my Kindle thatthere wouldn't be much of a resolution for this mystery.Little did I know there would be NONE! The greatestmystery about this is why Simon became a detective.He never thinks outside the box. His "guv" is alwaystrying to promote him, but why?Still I continue to buy and read Susan Hill's Simon Serrailer novels becauseof her other characters like Simon's sister Kat, her children, andothers in the community of this cathedral town. The quality of Hill's writing andher psychological insights keep me intrigued, but Susan if you writeanother stinker like this one, you might turn off this reader for good. Don'tdo that because I'm one of your biggest fans.
