51. Lady Killer by Elisabeth Sanxay Holding

Not the copy I have, sadly.

This was a lot of fun!  Young and beautiful (and was we learn quite strong-willed and practical) Honey Stapleton is taking her first ocean passage to the Caribbean with her old and uptight and very wealthy husband, Weaver.  Right from the beginning you can see the marriage is not doing well.  He is a total pill, worried about everything and super conscious about being proper.  He locks himself in the bathroom to change.  Honey, on the other hand, though aware that she doesn't love him, really does want to make a go of it.  She is realistic about her situation yet inherently positive.  She soon meets the couple in the cabin, Hilary and Alma Leshafer, next door and right away things seem suspicious.  They are a couple on their honeymoon but the wife's luggage never arrived and she almost missed the boat because she got a call that the departure was going to be delayed.

Though at first I thought it was going to be about the travails of Honey as a naive, out of her element young wife amongst the educated upper class set, right away you see that she is a pretty cool character.  She immediately recognizes that Hilary is super suspicious and Alma is way too in love to see it.  The book is fun because almost all the men are either jerks or deliberately oblivious while the women are more or less trying to work around their stupidity or evil.  The twist that comes at the end makes this even more fun.
