ASHES TO ASHES
Hardly a bygone time, but if you were dropped back a couple of decade, you'd feel a bit backwards.
Alex Drake didn't expect to be a police officer in 1981, especially since she was originally working in 2008. But after she was shot by Arthur Layton, she inexplicably regained consciousness in another decade. Now, while trying to get herself back into the right time zone, she's teamed up with the Metropolitan police and Gene Hunt to solve a few cases while she's there - and she's looking the part too.
When you're cracking cases in the roaring 20s - an era of jazz, elegant fashions and Art Deco opulence - it helps to have some style yourself. That's something Mrs Adela Bradley certainly isn't short on. Ignoring social conventions and sashaying through the world with a glint in her eye and a sly smile on her lips, she's always lavishly dressed - think leopard print coats, pin-striped suits, furs and pearls.
The one thing sharper than her fashion sense is her tongue. The countryside? "A place where the birds and animals wander about uncooked." A girls' finishing school? "A sort of farm where they grow wives and mothers." The criminals don't stand a chance.
Miss Jane Marple, the sparkling spinster of St Mary Mead, has had almost as many on-screen incarnations as Doctor Who. But many fans will plump for Joan Hickson as the definitive Marple. In fact, Agatha Christie herself wrote to a younger Hickson to say she hoped Joan would one day play the part.
Miss Marple may look like someone's doddery nan, but nothing escapes her casual glance. She's a little bundle of contradictions: sweet yet cunning, old fashioned yet worldly. Existing in a world of vicars and village greens, her gentle meddling spells trouble for the secret villains lurking within her idyllic landscape.
At first glance, Kate Warne is the goody-goody of this bunch. The standout character in The Pinkertons, she's prim, sensible and full of beans: like a Girl Scout with a gun. But there's real inner steel to her as well. There has to be: as a private eye in 1860s America, she's a woman with a man's job, and has to constantly prove herself on each and every case, whether she's helping take down train robbers or going undercover as a Southern belle to uncover the crimes of the early Ku Klux Klan.
As good with lab equipment as she is with a pistol, Kate is a forensic expert as well as a sleuth: think CSI in the wake of the Civil War.
Unlike the other women here, Sally Lockhart fell into mystery-solving for very personal reasons. It was the enigma surrounding her own father's death that first led her into the underbelly of the 19th Century, forcing her to draw on all her quick intelligence and life-saving resourcefulness.
She may be young, but she makes up for that in her unlikely skills (she speaks Hindustani and is rather good with a gun), as well as her sheer bravery in the face of murderers, opium dealers and the other unsavoury characters haunting the streets of Victorian England.
If there's one detective who could rival Mrs Bradley in the style stakes, it's Miss Fisher. She also inhabits the glittering world of the 1920s, except she happens to be almost literally a world away, in Australia.
Independently wealthy with a taste for fast cars and flying (she's a skilled pilot), the sleek and adventurous Phryne Fisher would give James Bond a run for his money. She's not simply a woman ahead of her time - even in the 21st Century she makes most people look like boring, shrinking violets by comparison.
