Do you want to start with A Dark-Adapted Eye? Barbara Vine is a pseudonym that Ruth Rendell started using in the mid-1980s.

Yes. There were two I liked. A Dark-Adapted Eye was the first one, and the second one was called A Fatal Inversion. I like Ruth Rendell very much as a writer, and I just found it amazing when she suddenly started writing under this new persona. And I thought the books had another level: it was as if she’d been holding back this extra skill. They were very different from the Ruth Rendells – and I just thought those first two were amazing…

When you say another level, what do you mean?

A greater depth. Because her early books – the early Wexford books – were very good, but fairly traditional police procedural whodunnits. Then some of the psycho-pathological ones like A Judgement in Stone were also very good and very creepy. But this seemed somehow a broader canvas, it seemed to involve more depth of character, and I thought it was remarkable that a good writer could suddenly get so much better.

The next one on your list is by Patrick Hamilton and is called Hangover Square. It’s set in 1939, and it’s about an unemployed alcoholic?

Yes. It’s a study of schizophrenia, in a way. The main character, George Harvey Bone, goes into these strange trance states. Like a lot of Patrick Hamilton’s characters, he is devoted to a woman who is not worthy of him, who is one step up from a prostitute. He’s obsessed with her, and eventually ends up murdering her. It’s just an incredibly written, claustrophobic book that would be in my top five almost any day you rang me. Patrick Hamilton goes in and out of fashion – and I’m not sure he’s ever been as popular in the States as he is in the UK – but a lot of crime writers like him because he has this strange claustrophobia. And he can be funny too, about fairly nasty things.

Yes, from the title I thought it might be quite funny.

There is a kind of black humour that comes through it – this central character who is so hopeless and is being exploited by his friends, and particularly by this woman. And you just know it’s going to end badly.

Tell me more about the claustrophobia.

A lot of it goes on inside his head. There’s one particular bit where he’s walking along in Brighton. Brighton figures a lot in the book. It’s actually set in Earl’s Court in London, but he goes down to Brighton, and Brighton carries a meaning for him. But there’s a very good description as he’s just walking along and his mood is changing, and there are things clicking in his mind and you can feel the threat of the mental illness about to take him over…

Let’s go on to A Kiss Before Dying, published in 1953, which a lot of people say is Ira Levin’s best book. Stephen King is hugely complimentary about Levin: ‘Every novel he has ever written has been a marvel of plotting. He is the Swiss watchmaker of the suspense novel; he makes what the rest of us do look like those five-dollar watches you can buy in the discount drug stores.’

He wrote A Kiss Before Dying very young: I think it was his first book. If you look at the history of the crime novel, the whodunits, where there was a puzzle and a device, were very popular in the 1920s and 1930s. But since World War II there have been very few books which rely on a trick – like, famously, the Agatha Christie where the narrator turns out to be the murderer. One would have thought that at the end of the so-called golden age, at the end of the 1930s, that all those tricks had been done. But in A Kiss Before Dying, there is such a device. I won’t describe it, because I don’t want to give it away, but it is a kind of verbal trick. And it’s one of those books where you get halfway through and you actually go back through the book and think, I know this, there’s a piece of information that has been kept from me… It’s also a very tense novel, again, about a murderer. But there is this central device that is so clever, that at the end you both hug yourself with glee at how good it is and kick yourself because you didn’t get it.

What do think it is that makes a really great whodunnit?

Like any good novel it creates a world of its own, and at the end of the book you know more about that world. In a crime novel it’s done through an investigation, normally a murder, but at the end you know not only who committed the crime, but you also know a lot about the environment that gave rise to this kind of pressure, the boil that was lanced by the murder. You’ve got to know the characters a lot better, and you know what pressures they were under.

Also, I think increasingly in crime novels, you know that crime is not without consequence. Because I think there was a danger with the golden age ones that they were nice little puzzles really. Murder was just a device to turn a key in an investigation, whereas now, in contemporary crime fiction, you’re much more aware of the consequences. I think it’s partly because we’ve lost the death penalty in England. In the golden age, it was wonderful: Hercule Poirot would get them all in the library and point at one person and say, ‘For zees reazons you deed it…’ and they’d go off and be hanged, end of story. But now, of course, the ramifications of crime and punishment are gone into more and there’s much more questioning of how close the criminal is to the investigation. Which was there from the start – look at Sherlock Holmes with Moriarty. It’s a very broad church now, crime fiction, and all kinds of things can fit into it.

You talk about creating a world of its own – when you set one of your series in Fethering in West Sussex is that because you wanted to explore that area?

It’s where I live, really. There are a lot of villages near Worthing in West Sussex – there’s Goring and Ferring and there’s one called Tarring. I thought Tarring and Fethering was a nice little private joke so I invented this village.

And the Charles Paris series, that was very much your life at that point as well, wasn’t it?

Yes, when I was a radio and television producer I was working with lots of actors – which actually I still do now as a writer. So I invented this antihero, who was about 20 years older than I was when I started writing. But then in about the tenth book I sort of froze him in the amber of his late 50s and I’m now rather older than he is. I’m contemplating writing another one at the moment.

I think there would definitely be demand for it. Here in my local library in upstate New York, in Goshen, I was taking out one of your more recent books and the librarian said to me, ‘Oh I love Simon Brett – you should read the Charles Paris series.’ It was particularly surprising, as the library doesn’t actually own any copies.

Well, I’m very chuffed. I think they’ve been out of print in the States for a long time, but who knows, maybe he’ll come back. He’s having a life here on radio: Bill Nighy is playing the part on Radio 4. It’s rather good casting. [http://www.bbc.co.uk/programmes/b00qld0x]

It’s wonderful to be taken back in time. You were writing those books in the 1970s – it was such a different era. Britain has changed so much, and to get insights into what daily life was like then, I find it really interesting, even just for that.

I remember once hearing someone say that if you are writing a book or doing some research about some time in the last 100 years or so, you should read the contemporary crime fiction. Not for your deep research of course. But it will give you a flavour of what people’s preoccupations were and what their entertainments were, and would be, I think, quite a painless way of starting research.
