Something old, something red, something stolen, something dead. Sunset Hall, a house-share for the old and unusual, is gearing up as energetically as its aged inhabitants can for Bernadette's big wedding day. However, with the RSVPs comes an anonymous note that threatens to cast a pall over the upcoming festivities. Agnes is in (somewhat begrudging) wedding planning mode and she and the not-so-sprightly gang of pensioners decide to hide the note from the betrothed, not wanting to cause stress. It is up to Agnes to dig into this poison-pen letter, determined to help the wedding go off without a hitch . . . aside from the bodies they've already had to hide from the blushing bride.
