**Second Book of the series.  Book 1 is in our archives. Stephen Spotswood’s second outing, MURDER UNDER HER SKIN (Doubleday, 368 pp., $23.99), furthers the adventures of my favorite new sleuthing duo, Lillian Pentecost and Will Parker, as they solve mysteries in a 1940s milieu evoking Nero Wolfe and film noir. And though it is clearly set in the present day, Richard Osman’s joyous THE MAN WHO DIED TWICE (Pamela Dorman/Viking, 352 pp., $26) evokes classic crime tropes with a mix of sparkling humor and emotion.
