Query: A brilliant novel.

"True Confessions" wraps a first-rate murder mystery inside a complex family drama that transpires within the genteel power of the Catholic Church. The story is made memorable (and frequently hilarious) by John Gregory Dunne's chuckle-a-page expositions of Irish Catholic foibles. Lt. Tom Spellacy of the LAPD, a semi-corrupt but competent detective, jousts with his partner, his superiors in the department, and his brother, the Rt. Rev. Msr. Desmond Spellacy, chancellor of the Archdiocese of Los Angeles. Dunne is to Irish Catholics as Philip Roth is to Eastern European Jews, and "True Confessions" is Dunne's "Goodbye Columbus"--a must-read.
