New Blood, Case 2 - Part Two

After a drugs trial participant is found dead, trainee detective Rash and junior SFO investigator Stefan are separately drawn to the case.

Rash tries to convince Sands the suspicious deaths are all connected, while Stefan has his drink spiked while pretending to be Leese at a party.

Rash and Stefan finally join forces, carrying out unauthorised interviews in a bid to uncover the truth about the drug trial and the dangerous pharmaceutical companies.

The fraud office receives a tip-off that three controversial skyscrapers have been greenlit by a government minister whose wife's company supplied the high-quality stone.

Eleanor is unimpressed by Rash and Stefan's behaviour and orders the Matherson investigation to be dropped - but thanks to information from Alison, they are soon back on the case.

When the accountant for a children's charity is stabbed after sharing his suspicions about financial irregularities, Rash and Stefan are thrown together yet again.

Rash and Stefan are convinced that Lisa killed her accountant and follow her to the hotel of a high-ranking politician - only to find more than they expected.
