The Agnes Sharp mystery series ends with a bang in this explosive finale from the author of Three Bags Full.

The octogenarian housemates at Sunset Hall are busy preparing for the wedding of one of their own, the blind and blushing bride Bernadette, but as the big day approaches, they must fend off a mysterious killjoy from the past.

Spring is in the air, and Sunset Hall is abuzz with anticipation of Bernadette's upcoming wedding. But not everyone is feeling celebratory. Namely, her best friend, Agnes Sharp, who isn't a fan of Bernadette's plan to leave the house share and its residents behind. Nevertheless, Agnes and the not-so-sprightly gang of pensioners launch into wedding-planning mode after a spot opens at the high-class Foxglove Manor--in just two weeks.

The minimum number of guests to even get the champagne fountain bubbling is twenty--a tall order for a reclusive couple in their eighties. Not to mention the high likelihood that their friend groups might not be compatible: Bernadette was once a police informant, while Jack, the groom, used to make a living in organized crime.

Just when they think they have the guest list squared away, a threatening note appears at the house. Agnes and the others decide to handle it themselves, not wanting to cause the betrothed stress. With some assistance from a private investigator (another person to add to the guest list!), Agnes digs into the case of the poison-pen letter, determined to ensure the wedding goes off without a hitch . . . aside from the bodies they've already had to hide from the bride. Will Bernadette and Jack happily ride off into the sunset together, or will this be sundown for Sunset Hall for good?
