HE OPERATES WITH LETHAL PRECISION...

Dr Harry Corbett is on his way to visit his estranged wife, Evie, who is scheduled for surgery the next day, for what he hopes will be a quiet evening of reconciliation. But, without warning, he arrives to find her dead in her hospital bed.

The police suspect murder, and Corbett is their only suspect...

Harry is unprepared for the stunning revelations that follow. Leading a double life, his beautiful wife had uncovered a deadly secret - and when the killer strikes again, Harry is once more the sole suspect.

Medically sophisticated, coolly arrogant, moving undetected through a busy urban hospital, it is clear to Harry that the killer can only be a doctor.

Can he stop the killer in his tracks before any more patients receive his lethal silent treatment?
