Moving the action to an exotic location is usually a sign of desperation when a character-based drama is flagging on home turf. New Tricks, most at ease in Soho and Stepney, hobbled into its tenth series with a two-parter set in Gibraltar – which is what passes for an exotic location in a show whose idea of the big chase is a sprint through the botanical gardens.

The basic set-up for The Heat is familiar – two mismatched cops are thrown together on a case and have to find a way of working together despite their differences in social background and methods – only in this case the officers are female. Add to the mix that the two actresses playing the roles are playing to type - loudmouth Boston street cop Shannon Mullins (Melissa McCarthy, almost reprising her Bridesmaids role) and prissy, super-bright but socially inept FBI agent Sarah Ashburn, as essayed by Sandra Bullock in any number of her films.

The ancients teach us that after hubris comes nemesis, and Luther's writer/creator Neil Cross has taken the lesson to heart. The big question hanging over this third series is, can the bullish DCI John Luther continue to hunt villains in his own headstrong, politically-incorrect fashion, or will he be brought down by snarling Detective Super George Stark, a bitter and vengeful man hauled out of retirement to bring Luther his come-uppance?

After a two-year gap, Luther returns to BBC One for a third series at the beginning of July. Devotees of Idris Elba's broody, enigmatic, rule-trampling 'tec may feel disgruntled that they're only going to get four episodes, but at least the great man is on stonking form.

You have to wonder if there any alternative themes permitted in TV drama apart from murder (preferably multiple, committed by a serial killer) or paedophilia. New five-parter The Fall plonks itself down squarely in category A, with its story of DS Stella Gibson (Gillian Anderson) from the Metropolitan Police arriving in Belfast to shake up a stalled murder inquiry.

I don't know how accurate Scott & Bailey is as a portrayal of the daily experiences of policewomen, but screenwriter Sally Wainwright is enjoying herself hugely with the chaotic private lives of her protagonists. Quite a bit of this echoes back to the death of barrister Nick Savage (the ineffably sleazy Rupert Graves) in series two. He was DC Rachel Bailey's lover, though he'd failed to mention that he was already married with two children. To heap insult on injury, she then discovered he'd had an affair with a juror during a court case.

It looks as if Broadchurch will reveal itself as a "town-with-murky-secrets" story, but on the evidence of this first episode we can expect it to be done with a skilful touch and a fine eye for detail. The trigger for the action is the death of 11-year-old Danny Latimer, but writer Chris Chibnall is focusing on the effect this has on family and friends as much as on the grim event itself.

I wonder if ITV ever imagined this Inspector Morse spin-off would last seven series? The opening pair of episodes in this valedictory season of Lewis still clocked over eight million viewers, though the numbers have subsided a bit since. Future one-off specials have not been ruled out.

A lot has happened since uncompromising French cop drama Spiral was last on our TV screens in May 2011. More of continental Europe has arrived. Attention has shifted northwards to Denmark for The Killing and Borgen. Sweden’s Wallander and Sebastian Bergman were never far. The Bridge closed the gap between both countries. French contender Braquo threw down the gauntlet too, but it was never going to steal Spiral’s thunder as it was just too cartoony, too brutal to clench to your bosom.

How could we have expected the London 2011 riots to be brought back for the big screen? The least likely answer must be as a black comedy about a bicycle cop who after a bad concussion has woken up as a one-man vigilante who’s taking out the villains on his beat, but asking their permission first. That last detail explains the title of Stuart Urban’s May I Kill U?, which brings this particular wayward member of her majesty’s constabulary rather into Carry On territory, with a twist of Ealing comedy on the side.
