BOOK REVIEW: Y Is for Yesterday by Sue Grafton
We’ve made it to Y, the final book in Sue Grafton’s beloved Alphabet Series.
In Y Is for Yesterday, private investigator Kinsey Millhone becomes involved in a case surrounding a group of former high school students and a terrible secret from their past. Years earlier, a cheating scandal, a videotape, and the murder of a classmate changed their lives forever.
Now, one of them has been released from prison, and someone is using that old videotape for blackmail. Kinsey is hired to find out who is behind it, but the deeper she digs, the more dangerous the situation becomes.
At the same time, trouble from Kinsey’s own past has returned, adding even more suspense to the story.
Our review: ⭐⭐⭐⭐⭐
Y Is for Yesterday is a fitting final adventure for Kinsey Millhone. It has mystery, danger, secrets from the past, and the determined, independent Kinsey that readers have come to know throughout the series.
Sadly, Sue Grafton passed away in 2017 before writing Z, so the Alphabet Series ends with Y. As her family famously shared after her death, “the alphabet now ends at Y.”
