Not Dead Enough by Peter James

There's a serial killer on the loose in Brighton, England.  Socialite Katie Bishop has been found murdered in her home, left to be found in bizarre circumstances.  Her husband, Brian Bishop, owner of a very successful software company, is of course the main suspect.  When his girlfriend is found days later also murdered and in the same bizarre circumstances, the net tightens around him and he is charged with murder.

Detective Roy Grace heads up the investigation.  He is in charge of a team of detectives and his career is headed in the right direction.  He has adjusted to the disappearance of his wife nine years before and has recently been seeing a new woman.  This adjustment is challenged when an old friend returns from holiday and states that he has seen Roy's wife while in Munich.

There are currently eight novels in the Detective Grace series.  This one is the third.  It is a good mix of police procedural and character development with all the safeguards and procedural steps that are followed in an investigation being fully explained.  James is considered one of the foremost crime writers working and one of England's finest.  This book is recommended for mystery readers.
