When her week begins, Rarity expects the biggest mystery she'll need to solve is how a rare first edition of Lewis Carroll's Alice in Wonderland ended up in her bookstore bathroom. But after book club member Shirley tells her that her husband George, who has dementia, is the prime suspect in a nursing home murder, Rarity feels as if she's stepped through the looking glass.

As someone who's been given a second chance at life, Rarity wishes her friend Shirley a second chance at love. But Shirley has rebuffed her senior suitor Terrance out of loyalty to George, even though he no longer knows who she is. Except guess who's the second suspect? Shirley's caught between two men--and it's up to Rarity and the survivor sleuths to determine if one of them is capable of cold-blooded murder . . .
