A good mystery series with a science hook

I've been working my way through Camille Minchino's mystery series with a physicist detective. The first in the series is The Hydrogen Murder. The main character is Dr. Gloria Lamerino, a recently retired physicist who has moved back to her old home town near Boston. She's a very enjoyable character - reminded me of an older Miss Zukas (Jo Dereske's mystery series with a librarian detective which started with Miss Zukas and the Library Murders) or Christine Bennett (Lee Harris' series with a former nun detective which began with The Good Friday Murder). All of these protagonists have had restricted social lives (for various reasons) and develop over time. While some of the books in this series are weak, I've enjoyed all of them so far. My favorite of the Lamerino mysteries so far was The Carbon Murder, with the nanotubes and buckyballs providing the background for the mystery.
