It doesn’t take much to raise the dead. A couple of bills; a name; a postcode; nothing that can’t be found in any old domestic bin-bag, torn apart (perhaps by foxes) and left on the doorstep like a gift. You can learn a lot from abandoned mail: names, bank details, passwords, e-mail addresses, security codes. With the right combination of personal details you can open up a bank account; hire a car; even apply for a new passport. The dead don’t need such things any more. A gift, as I said, just waiting for collection.

Sometimes Fate even delivers in person, and it always pays to be alert. Carpe diem, and devil take the hindmost. Which is why I always read the obituaries, sometimes managing to acquire the identity even before the funeral has taken place. And which is why, when I saw the sign, and beneath it the post-box with its packet of letters, I accepted the gift with a gracious smile.

Of course, it wasn’t my post-box. The postal service here is better than most, and letters are rarely misdelivered. It’s one more reason I prefer Paris; that and the food, the wine, the theatres, the shops and the virtually unlimited opportunities. But Paris costs – the overheads are extraordinary – and besides, I’d been itching for some time to reinvent myself again. I’d been playing it safe for nearly two months, teaching in a lycée in the 11th arrondissement, but in the wake of the recent troubles there I’d decided at last to make a clean break (taking with me twenty-five thousand euros’ worth of departmental funds, to be delivered into an account opened in the name of an ex-colleague and to be removed discreetly, over a couple of weeks), and had a look at apartments to rent.

First, I tried the Left Bank. The properties there were out of my league; but the girl from the agency didn’t know that. So, with an English accent and going by the name of Emma Windsor, with my Mulberry handbag tucked negligently into the crook of my arm and the delicious whisper of Prada around my silk-stockinged calves, I was able to spend a pleasant morning window-shopping.

I’d asked to view only empty properties. There were several along the Left Bank: deep-roomed apartments overlooking the river; mansion flats with roof gardens; penthouses with parquet floors.

With some regret, I rejected them all, though I couldn’t resist picking up a couple of useful items on the way. A magazine, still in its wrapper, containing the customer number of its intended recipient; several circulars; and at one place, gold: a banker’s card in the name of Amélie Deauxville, which needs nothing but a phone call for me to activate.
