Mary Alice has spared nothing for her only daughter’s wedding—providing enough gourmet food and glittering elegance to make Sister think seriously about finding herself a rich fourth husband to pay for it all. Practical Patricia Anne has put away her aunt-of-the-bride blue chiffon and settled back into domesticity when fun-loving Mary Alice informs her that they have a post-wedding date with a genealogist from the groom’s side of the family.

And the sisters are only just finishing their departed luncheon companion’s cheesecake when the police arrive.
