The Fix by David Baldacci

Third in the memory man series about Alex Decker, a man who was in one place in the NFL and suffered from the hit.  Now he has synesthesia, where he sees colors representing what he sees, the most prominent being blue for death, and hyperthymesia, a perfect memory, whether he wants to remember or not.\

In this case, as he is walking to work one day, a man kills a woman then himself in front of the Hoover building.  Decker's team is pulled off of cold cases and given this case to solve.  What it leads to is bigger than a simple murder.  The man was a contractor with a meeting in the Hoover building, the woman was a hospice volunteer and substitute teacher with no apparent connection to the man.

It's up to Decker and his team and friends to solve what turns out to be a much bigger case than anyone expects.

This is worth analyzing.
