Old guilt and new sins create a tangled puzzle in McGilloway's outstanding second Inspector Devlin mystery (after 2008's Borderlands
). When Garda Insp. Benedict Devlin discovers the crucified body of James Kerr, an ex-con who claimed he'd returned home to forgive the gang members who betrayed him after a robbery, Devlin sets out to solve that slaying as well as the original robbery, which have links to drug thefts, brutal attempted rapes and additional murders. Devlin, who also has to cope with backstabbing fellow policemen and can't help getting personally involved in his cases, suffers from attacks of panic and conscience that push him to work harder, even when his wife and boss suggest he ease off. This quietly compelling procedural contains much buried passion, especially in the never acknowledged mutual attraction between Devlin and his female partner. Readers will be gripped as they watch this driven Irish detective seek his place in the moral landscape. (Sept.)
