There are a zillion places to set a novel, even more if you include locations that don’t exist yet, but this side of the pond London is at the top of the list.

It’s no surprise that London’s attractions shape my writing: I was born in the capital, and after a junket of a decade or two came back here to live and work. But even if you’re not a Londoner there are plenty of good reasons to set your action there.

1 Things happen all the time in London: knife crime, break-ins, births in hospital carparks. So you can slip in a fictional car-crash or multiple murder and it won’t seem nearly as odd as it might in a dozy village.

2 London is incredibly romantic, even in the rain. That means lots of places for your characters to wander arm in arm in Highgate cemetery, should you wish them to. 

Or, if you prefer, to argue on the top of Primrose Hill.

3 Everyone knows something about London. Its iconic features can be used as a kind of shorthand, such as the Tower, the London Eye, and the Tube. However, if you want to include real detail, there’s no substitute for the author joining the melée and checking it out.

4 Medieval buildings can be found all over the place, including smack dab by Big Ben.

Then again, there’s no shortage of great new architecture, and more to come, judging from the number of cranes.

5 It’s very green. Should your characters wish to stretch their legs, or their children’s, offer them Regent’s Park, Clapham Common, or perhaps just a walk by the Thames. Time it right, and they can watch Tower Bridge open.

6 London is very diverse, with some parts that are distinctly upmarket, like trendy Marylebone, where my novel One Night at the Jacaranda kicks off.

I’ve also included Edgware Road, where you’d be hard put to find any newspapers that aren’t in Arabic.

There, groceries spill out onto the pavement, with watermelons as big as Beirut, and shiny aubergines, pearly white onions and wrinkly green things that I’ve forgotten the name for, all lying with fat bunches of sweet-smelling herbs.

On the street there are always clusters of young men in T-shirts and jeans, standing on corners as they shout into mobiles or talk urgently with their hands, and, during the annual Saudi summer invasion, streams of women with pushchairs, most of them in a black abaya, some veiled so you could only see their eyes. They glide by, with their Fendi handbags and large retinues of children, while older men sit outside cafés and juice bars, smoking shisha. The men stared hard at passers-by, at any passing Mercedes. They have nothing else to do.

No surprise my next novel is also set in London.

7 It’s full of characters, like the woman walking down Finchley Road with a black bin liner under her hat. And when I say walking down Finchley Road, I mean in the middle of the bus lane. Or the man in Goodge Street dressed from head to foot as an African grey parrot. This being London, nobody gives either of them a second glance.

8 Finally, consider the US market: to Americans, London IS Britain.
