However Michael has gone into hiding but soon gives himself up, yet gay Chicano lawyer Henry Rios is not convinced that Michael is the killer despite his confession. While the case is otherwise weak against Michael, Henry's only real hope of clearing Michael is to find the real killer, but the facts point to an even more unlikely suspect.
In fighting Michael's case Henry finds himself battling against the politicians who want a speedy resolution. However Henry is also under even greater pressure in his personal life. His lover Josh, now slowly succumbing to AIDS is about to leave him having found someone else.
In trying to come to terms with the situation Henry must also face his own personal demons.
Hidden Law, the fourth Henry Rios mystery is yet another finely crafted and well written suspense story from Californian lawyer Michael Nava. Fine characterisation, crisp succinct prose and careful attention to detail, along with a most likeable hero who is courageous and yet self effacing and compassionate make these novels compelling reading.
