Sarah finds a strange mirror that, though unbroken, proves to be very bad luck.
According to Max Bittersohn, he and Sarah Kelling have witnessed enough murder and unhappiness, so it's high time they got married. And though Sarah hasn't yet agreed to such drastic measures, she invites Max to summer with her at Ireson's Landing. But they haven't been in the house ten minutes when they stumble upon summer's first mystery — a mint-condition, antique Spanish mirror that is tremendously rare and valuable. Sarah has never seen it before and she doesn't know how it ended up in the summerhouse, but the sleuthing couple will soon find this looking glass to be more troublesome than anything Lewis Carroll ever invented.
As the zany Kelling clan descends on Ireson's Landing, Sarah and her beau try to uncover the mystery of the Bilbao looking glass — a quest that is disrupted when a vicious next-door neighbor is found hacked to death with a woodshed ax. By summer's end, Sarah and Max will learn that some murders can be solved simply by looking in the mirror.
