This time it's strictly business. Former policewoman Glen is now a PI too, and with a much classier clientele than Cliff's - she's been told 'money's no object' by her latest, a wealthy family from Sydney's eastern suburbs. Together, Cliff and Glen take on the case of Rodney St John Harkness, recent inmate of a mental institution and a recovering alcoholic with a murky, possibly murderous, history. But Glen is also a recovering alcoholic - and the combination proves disastrous. When Rod and Glen vanish, Hardy finds himself in a race against time to untangle Harkness' tortured past and find the pair. The trail leads up to the central coast and some of Sydney's best-known beaches. Will Cliff be in time, or will the 'salty tang of blood' fill the air?
