AFTER DARK (4.5) by Wendy Etherington Another winner from Etherington with great humor and unexpected characters. Historical society director Sloan Caldwell tries to talk the owner of the most famous house in town into showing it off. But the mysterious Aidan Kendrick has suffered a family tragedy that resulted in publicity and gossip. Despite their attraction, he isn't sure he can get involved. Then a body appears on his porch. Has his past followed him? A great hero and heroine are highlights, but it's the clever touches that are so enjoyable: Aidan and Sloan's last boyfriend each trying to claim her, then getting drunk together; Sloan's father, the sheriff, so well drawn he leaps off the page; and the local computer expert, a community-raised child.
