Superposition

Superposition by David Walton is a mystery adventure that is most fascinating for its use of quantum physics in both positing the murder and telling the story.  Jacob Kelley is a physicist who is accused of killing a former colleague found dead.  He is arrested and put on trial for murder so must of course work out who really did the murderous deed.  The whole thing is complicated by the fact that the murdered guy had been working on quantum computing and had found a way of achieving macro level quantum effects. 

The physics as explained in the book was fascinating.  The mystery was a bit too easy to figure out, I knew the real killer before any of the book characters did.  In addition I really did not like Jacob (our narrator).  I found him surprisingly violent and irrational for someone who is supposed to be an intelligent scientist.  Now I suppose scientists can be violent but the irrational part seems less likely.  I would recommend the book for the fun science ride and say ignore the obviousness of whodunit as well as the fact that you wind up wishing an unhappy ending for our hero.
