I’m reviewing both books at the same time. I read I Know
Everything first and was blown away. I had to order What Have You Done
immediately and dug in eagerly. It might have blown me away, if it had been the first one I read
by the author. That’s because they’re only slight variations on the same story.
I Know Everything is a combination psychological thriller
and police procedural. So is What Have You Done. Both books have central
figures who earlier in life were subjected to heinous emotional and physical
abuse. Both begin with the murder of a woman of importance to the central
figure. Both end with a reveal that leaves law enforcement not looking good. In
the interim there are good guys and bad guys, lots of tension, plenty of skullduggery
and mystery. The writing is good, the characters are largely believable, the
police procedures are genuine and the information about psychological stress
and techniques of gaslighting is accurate.. I had the ending figured out around the 80-85% mark
in Everything. Unfortunately, I had the ending to Done wrapped up before
the 50% point in the book. It would have been sooner except that I was
reluctant to conclude that such a fine author had simply told the same story
twice.
