THE ROME AFFAIR
Oddly, Rachel's fling strengthens her bond with Nick. But something else has changed too: Kit's suddenly acting strangely, threatening to reveal Rachel's indiscretion and demanding money to keep silent. Sickened, Rachel complies -- until the situation spirals out of control and there's much more at stake than her marriage.
Caldwell expertly plucks at the reader's nerves, building dread and doubt at a slow but deliciously inexorable pace. Almost Hitchcockian in its execution, this novel has the feel of a '50s film noir. (Jun., 384 pp., $6.99)
