Erhart (Bully Creek
) steers clear of the earnest obsessions that weighed heavily on her early books in her fifth outing, a quaint novel of the American West enlivened by a quirky mystery. En route from St. Louis to visit her in-laws in Flagstaff, Ariz., young Jane Merkle meets two women botanists on the train. Their paths cross again after Jane, having lost her luggage and traded her fancy dresses for dungarees and a butterfly net, becomes enthralled with her new surroundings and ranger Euell Wigglesworth. As it turns out, Elzada, one of the botanists, is in town to help investigate a 13-year-old murder, and as the mystery unfolds and dark secrets come to light, the canyon works its magic on Jane. Erhart, a river and hiking guide, teases her readers about the sweet silliness of human affairs in the face of the magnitude of nature, and the cleverly plotted mystery becomes a lark of a vehicle for Erhart's thoughtful prose. This novel is light and agreeable, touched with just the right amount of awe at the splendors of nature. (Dec.)
