The six-part series will see Dougray Scott reprise his role as troubled detective DI Ray Lennox, after his unhinged portrayal in series one garnered a recent nomination for an International Emmy.

Following his breakdown after bringing Mr Confectioner to justice in series one, Lennox returns to Edinburgh Serious Crimes ready to prove his recovery. But in the interim, Chief Superintendent Bob Toal (Ken Stott) has lost his mojo and Lennox's partner Amanda Drummond (Joanna Vanderham) has been promoted.

Coupled with the two new faces on the team, the devious Tommy Stark and failed actor Norrie Erskine, the new department will take some getting used to.

When one of his former colleagues is attacked, Lennox and Drummond team up to crack the case, one of "vengeance, identity and social justice." The attack is linked to a gruesome attempted murder of an Establishment figure at a luxury hotel that had been kept secret from the police. And as Lennox investigates, he begins to suspect an Establishment cover up.

John Simm (Grace) and Derek Riddell (Silent Witness) will also return for the second season, and Dougray Scott’s son Gabriel Scott (House of Dragon) will appear alongside his father.

Rebecca Root (The Queen's Gambit) David Elliot (Kajaki), Laura Fraser (Breaking Bad), Fiona Bell (Shetland) Sarah McCardie (It’s A Sin), Brian McCardie (Murphy’s Law), John McLarnon (Outlander), Ewan Miller (Skin) and Gordon Morris (The Forgotten) will also feature.

Directors for the second series include Trygve Allister Diesen (Wisting) and Anthony Neilson (The Debt Collector).

Welsh said: “I loved working on the first season of Crime, and Dean Cavanagh and myself are already having a blast developing scripts for the second series. It was wonderful to work with such a talented cast and we hope to push those memorable characters further this time. No more Mister Nice Guy from Dean and I.”
