One of the various book feeds I get highly recommend a recent Louise Penny book, number something-or-other in this series. So, back to the start. I just had such good luck reading a series in order, and over the years, this name keeps popping up as literary fiction, of a thriller variety. Cop procedural, to use the TV moniker. Murder mystery?
Still Life seemed to be the first in the series.
One author, a passage in one of his books, suggested that his character would take up astrology, and writing cozy murder-mysteries.
Now I get the reference.
