Dig by C.R. Corbin is the second book of the Morgue Mama mystery series set in the contemporary (fictional) small town of Hannawa, Ohio. Maddy Sprowls "Morgue Mama" has been head librarian for the local newspaper for decades. Each morning she starts her day precisely at 9 with a cup of tea, reading the obituaries. When she reads the obituary for a dear friend, university professor Gordon Sweet, she's shocked and saddened. When she finds out "Sweet Gordon" was murdered at the archaeological dig he directed, she's determined to make sure his killer is caught and punished.
She persistently investigates the details of Gordon's life. She contacts fellow members of Meriwether Square Baked Bean Existentialist Society, her beatnik club back in college days. She believes Gordon's death is linked to another death from 50 years ago. The police don't believe her, so she sets about investigating that death as well, to prove the link. Of course, she is right.
She's a tough, smart and sassy protagonist. As a senior citizen, she's frequently ignored and/or underestimated; factors she uses to her own benefit. She diligently pursues all clues, encountering many red herrings until she at last uncovers the truth.
I look forward to the third (and final) book of the series, The Unraveling of Violeta Bell.
