by Mary Higgins Clark
I think I've read all of Clark's mysteries* so when I noticed her most recent one, I picked it up. It was good. I'd probably rate it 3.25 stars, if I still did ratings.
Carolyn's brother has been missing for years; the only contact she and her mother have with him is when he calls every year on Mother's Day. After Mac's last call, Carolyn decides she is going to search for him. Her actions put her life in danger and has the reader guessing about the people she comes in contact with and what motivates some of their actions.
*I looked on amazon.com and discovered Clark has another recent book I haven't read, I Heard That Song Before, and she has a new one coming out in April, Just Take My Heart.
