Hilda Johansson Cavanaugh finds herself caught between the world of her past as a housemaid and her new role as a wealthy wife in Agatha-winner Dams's delightful sixth mystery set in early 20th-century South Bend, Ind. (after 2005's Crimson Snow
). When Hilda's only friend's husband is accused of stealing, arson and murder, Hilda determines to prove him innocent. Meanwhile, as part of her efforts to belong to society, Hilda joins a group of well-to-do members of the community in creating a Christmas party for street boys, some of whom she hires to help in her investigation. The mystery, which evolves naturally and slowly, tends to get lost amid the subtle and sometimes not so subtle social commentary on such matters as the friction between Hilda's Swedish Lutheran family and her husband's Irish Catholic relatives. Still, series fans will be well satisfied. (Sept.)
