American Catholicism was once so scarlet with absolutes and certainties that glamorous converts would fall on their knees before Bishop Sheen, while intellectually rebellious communicants, along with the sexually guilty, would flee in angry, soul-risking apostasy. To those of the faithful with long memories, the new Church, forty years into its age of reform, seems as blandly embracing as Unitarianism—less Hail Mary than hail-fellow-well-met, with its handshakes of peace toward the close of a mass that's more "participatory" than a PTA meeting.
The post-Vatican II Church has been as much a problem for fiction writers as for conservative bishops. Liars and Saints, Maile Meloy's engaging but slapdash first novel, is something of a case in point. The author gives us more than fifty years of the Santerre family, California Catholics, but clearly knows that the pre-1960s religious material—heart-in-mouth confessions; fervent collecting for the missions; ecstatic conventual retreats—is stronger, gaudier stuff than the modern, guitar-strumming version that eventually demoralized the Church's laity and, in a sort of reversal of the loaves and fishes, decimated its priesthood. Meloy wisely stays away from much consideration of the latter, though it has to be said that even her old-time religion is mostly a motif that helps to string four generations of Santerres into a narrative rosary for a novel that otherwise has the big familial concerns of commercial fiction on its mind.
Good-looking Teddy and Yvette marry during World War II and stay together, despite Teddy's over-the-top jealousy. He could always arouse himself sexually with fantasies of Yvette's infidelity, and her admission that she received a photographer's kiss while he was over in Korea leaves them to "[settle] into a life together that felt like a truce."
The couple's two daughters—obedient Margot and more rebellious Clarissa—serve as opposites in the manner of a parable, though it's the teenage Margot who winds up pregnant by Mr. Tucker, the dancing teacher who comes to give lessons at Sacred Heart High. Hustled off to sympathetic relatives in France, she gives birth, in 1959, to a boy named Jamie; her mother, the still youthful Yvette, manages through travel and trickery to pass the infant off—even to Teddy—as her own son. This smoldering family secret is able to remain one for as long as it does in part because of Margot's aversion to the baby; for years after his birth, even when the childlessness of her marriage appears to be permanent, she wants almost nothing to do with Jamie, whom his "sister" Clarissa loves much more demonstratively.
It's plausible that Jamie in his early thirties would push against emerging cracks in the cover-up in order to find out the truth. It's less believable that he would fall into a second bloodline-bending imbroglio, fathering a child by Clarissa's daughter, Abby. T. J., the baby born to them, is almost comically suggestive of the Trinity, uniting as he does the family's interchangeable generations.
