Reach (The Blake Harte Mysteries #4)
Robert Innes

Sure enough, somehow, Kerry is found dead in her top floor apartment - a place that was being guarded by Blake and the apartment's security. How is it possible for Kerry to have been murdered in her apartment when nobody could have gotten in or out?
Did Thomas Frost somehow manage to murder Kerry from his prison cell? Who else could want to see her dead quite as much? As Blake and the team attempt to stop a killer who is seemingly capable of anything, he could never imagine that for somebody else in Harmschapel, time is also ticking....Gay
