It's going to be a long slog through the mud and blood of the Great War commemorations, but we're going to learn a lot along the way. Coming up next month on BBC One is The Crimson Field, a new drama about nurses on the Western Front in 1915. Specifically, the action takes place in the fictional Hospital 25A near Étaples, where battlefield casualties find themselves being tended by a mixture of stalwart career nurses and the inexperienced young woman of the Voluntary Aid Detachment (VAD).

In its infancy back in 1997, Jonathan Creek felt fresh and inventive, with clever little swipes at the entertainment industry and a new take on crime drama: not who or why, but more of a howdunnit. Its star Alan Davies, he of the duffel coat and the tumbling hair, was rather good at narrowing his eyes and staring into space while we let our hot chocolate go cold waiting to discover not only who carried out one of those incredibly theatrical murders, but to see its baffling mechanism unpicked.

A new series about a team of London firefighters? Probably a bit like Casualty meets The Bill, with added smoke and cats stuck in trees. But no - writer Lucy Kirkwood (of Skins fame) has created a raw chunk of contemporary drama which isn't afraid to rip up a few preconceptions.

Crikey. Line of Duty was pumping dangerous levels of octane first time round. For this new series we’re in for an overdose. After one hour the body count is racking up: 3 coppers (shot), 1 witness under protection (burned to a crisp), AN Other (defenestrated). Plus that lovely soft Keeley Hawes has been waterboarded in the lav and has assaulted a noisy neighbour with a wine bottle. If it’s cheering up you need, best retreat to Call the Midwife, where they have window latches you can trust.

Mothers and their sons provided the framework for the latest story involving DCI Alan Banks, the character on whom ITV is pinning its hopes to fill the vacancy of the nation’s favourite detective now that Frost and Morse are no more. Peter Robinson’s series of novels has been enjoyed for more than 25 years, selling millions in the UK and translated into more than 20 languages, but it took until 2010 to reach our television screens with Stephen Tompkinson in the starring role.

Since Nashville and country music are one giant soap opera, it's amazing nobody turned Tennessee's Music City into a TV series before. No matter. Here we are with series two, and it's as deliriously cheesy and melodramatic as ever.

“I like it when you’re a bastard,” George Gently growled at his sidekick, halfway into the first episode of this sixth series set in 1960s Northumberland, reassuring us that the partnership is very much back on when all appeared to be lost the last time around. And what a terrific opener it proved to be.

The annual reappearance of The Good Wife is always a cause for celebration. Why they persistently park it in the twilight zone of More4 remains one of the enduring mysteries of our era, since it's one of the best shows on TV, but the only question that need concern us is: will season five be as good as the ones that came before? On the evidence of this opener, yes indeed, so much so that American critics have been hailing it as the best ever,

Such is the level of confidence that the Silent Witness producers have in their new ensemble that star turn Emilia Fox barely lifted a scalpel in the latest instalment of the BBC’s long-running crime series. Either that or she needed a night or two off, and who could blame her? It's now in its 17^th series, and Fox has stuck it out for more than half of them.

It’s costume drama meets adventure story, it’s got smouldering manhood and heaving-bosomed women with sex, swordfights, politicking and even beautifully lit Prague doubling for 17th-century Paris, but the question hanging over the BBC’s lavish new Sunday-night primetime series The Musketeers is: what exactly is it? And then Hugo Speer’s Captain Treville loses patience and barks: “You three, my office, NOW!” and it hits you: this is Charlie’s Angels in thigh-length boots.
