Book ~ "S is for Silence" - Sue Grafton (2005)

From Goodreads ~ Cases don't get much colder than that of Violet Sullivan, who disappeared from her rural California town in 1953, leaving behind an abusive husband and a seven-year-old named Daisy. But P.I. Kinsey Millhone has promised Daisy she'll try her best to locate Violet, dead or alive. Kinsey tries to pick up a trail by speaking to those who remember her-and perhaps were more involved in her life than they let on.

But the trail could lead her somewhere very dangerous. Because the case may have gone cold, but some peoples' feelings about Violet Sullivan still run as hot as ever.

I've read all in the series and have enjoyed them, though I found the last couple bland. I really enjoyed this one but as per the reviews I've read, it ended very abruptly. After investing so much time into the story, I needed to have things spelled out like the why and how. Quite bizarre!
