Peggy Kelleher is teaching “Murder & Mayhem in the Ancient World,” part of Lifetime Learning at Snow Library, on Tuesdays beginning March 30th, from 10:30 a.m. to noon. The first class will focus on the House of Atreus, the second on Orestes and Electra, and the third on Oedipus. You’ll come out of it feeling pretty together by comparison. Registration is $10 at friendsofsnowlibrary.org.
