Margaret Maron’s Three-Day Town, which, per SYKM, won the 2011 Agatha Award for Best Novel, is on sale at Kindle and Kobo US right now (February 8, 2021) for $1.99. It’s the 17th in Maron’s awesome Judge Deborah Knott series, and but the storyline also includes Maron’s other also awesome detective, Lieutenant Sigrid Harald of the NYPD.
