Ira Levin is one of my favorite writers. While his stories are a bit far-fetched (as with "Rosemary's Baby", "The Boys From Brazil", and "The Stepford Wives") they are always entertaining. His first book, "A Kiss Before Dying", is now largely forgotten (..it was written nearly 50 years ago) but seems remarkably fresh.
In "A Kiss Before Dying" we have a a rich college girl and her gold-digging boyfriend in a dilemna. The girl is pregnant and the choice ahead is grim: either get married and lose daddy's money, or risk an illegal abortion (remember this book takes place circa 1950). She prefers the former, he the latter. The outcome of this dilemna is unexpected (no spoilers here), and the story then really kicks into gear. Yes, in true Levin form the plot is a bit contrived. But it is deliciously readable.
Bottom line: strongly recommended.
