Kate investigates a serious fire at a suburban chemical storage facility. What starts out as a routine investigation into another bulk chemical accident becomes murkier and more tangled, as suspicion swings from the owner of the emplacement to the greenies who are trying to shut it down. There is also a suspicion that Mills and the State Government are an interested party. Trimble investigates the suspicious death of a mystery woman in a non-descript suburban house. Nothing adds up until he and Daniel discover she is a prostitute who dispenses tea and sympathy rather than titillation to a high-up government official. Julie at last finds her place in the sun with the charming Naval Executive Officer. Kate farewells Liam.
