On Eeny Meeny I'm Not So Keeny

I may have reached a point that I never anticipated. After reading fiction for 60 years, and writing it for 15, perhaps I've seen too many plots, because I'm having more and more trouble finding books which genuinely surprise me. Eeny Meeny by M. J. Arlidge, a crime novel, is the latest book whose plot line seemed easy to predict.
This isn't to criticize the writer, who did his/her best to follow the tried and true thriller progression (things get worse, over and over, until the climax) but there are only so many twists and turns one can imbue a story with when the setup is typical--In this case, a modern-day English policewoman detective pursuing a serial killer.
M.J. does one thing that I find irritating, and I blame James Patterson for this; he/she writes 3-page chapters, flitting from one point of view to another. I like to settle down with a scene, enjoy some rich details, and will even tolerate some business that doesn't exactly advance the plot.
The author does try very hard to distinguish this hero, Helen Grace, from other DC's such as Peter Robinson's with attributes that have shock value, but there is some more subtle character development lacking, in my opinion. Since this is the initial book in a series, perhaps Grace becomes more deep and rounded as the overall arc progresses. That happens sometimes.
Or perhaps I've simply read and written too much in the genre to wholeheartedly enjoy overly familiar tropes. I hope not, but evidence seems to trend that way.
