Never share your Uber account could be the moral of this pacy, nasty little thriller set in two-faced New York: one shabby, one so very chic. Emma Wodehouse meets Tom Ripley, as it were.

This is not one of his Jackson Lamb novels, but Herron’s standalone thrillers are also excellent. Here we have a woman trying to make ends meet in a lonely London sublet who turns out to be just the person MI5 needs to thwart an international plot that puts all of Britain at risk. Who’d have thought?

Not one but two unreliable female narrators in this ominous tale of memory and obsession, lent exoticism by its fever-dreamy setting in 1950s Tangier.
