It was that she didn’t know for sure whose baby she was carrying. The odds were, it was Danny’s. They had ended their affair five weeks ago, but in the three weeks prior to that-the three weeks after her last period-they had made love at least a dozen times. She’d only had intercourse with Warren twice since her last period, both times after she and Danny had ended it. She hadn’t even wanted sex with Warren, but how else could she make an honest try? And what alternative did she have but to try, given Danny’s decision? Walk out on Warren to live alone in some lonely apartment, surrounded by other divorcées and waiting for a man who couldn’t come to her for another fourteen years, if ever? Not an attractive option even before she was pregnant. Now…

Laurel wasn’t even sure whether a fetus conceived while you were on the pill was viable or not. She would have to look it up on the Internet. She should already have done it, but that kind of practical act didn’t square with her strategy of intense denial. She still couldn’t believe she was pregnant. She was on the pill, for God’s sake! Ninety-eight percent effective! How could she be in the unlucky 2 percent? She’d had some bad luck in her life, but never the worst luck. It was the rotavirus, she knew. Last month, she had somehow contracted the same gastrointestinal virus that had required the quarantining of major cruise ships. CNN had said the virus was sweeping the country: people were simultaneously puking and pooping from coast to coast. Three to five days of that, Laurel had learned, could eject from the system the progestin contained in a woman’s birth control pills. Since she’d had sex almost every other day last month, pregnancy must have been a near certainty.

She laid her forehead against the steering wheel and allowed herself a single sob. She’d always believed she was a strong woman, but now fate had colluded with chance-and stupidity-to make the prospect of raising an illegitimate child in her husband’s house a reality.
