Most of the stories in this collection have the familiar, light hearted Greene tone. The quality varies wildly, though. Some stories, typically the longer ones, are among the best of what Greene has written (the tragicomic 'May we borrow your husband?', about two gay men who prey on a newly wed but seemingly unhappy couple, being my favourite).
Others, often written on commission from magazines, breathe routine. Not bad, but forgotten once the page has been turned. In any case, don't read the whole book immediately, but take it in chuncks to avoid a Greene overdose.
