I just finished Altered Carbon by Richard K. Morgan.

Altered Carbon is a science fiction noir novel, where an investigator with little power tries to find the truth while battling against entrenched, corrupt and usually perverse, powerful people.

In this case, the investigator is a an ex-super soldier, ex-crook brought to Earth to investigate the death of a wealthy man which might be murder and might be suicide.  This is complicated because people have their personalities stored in chips or backed up and can be housed in any body, so the man has been brought back to life, and the protagonist has been "sleeved" in an ex-cop's body.

It develops in pretty predictable ways, but is a decent read.
