Lieutenant Eve Dallas faces a grisly double homicide when two young lovers, both employees of the same prestigious accounting firm, are brutally killed on the same night. Eve must balance solving this case with organizing a baby shower for her friend Mavis, but that's what friends are for.

Mavis needs another favor. Tandy Willowby, one of the moms-to-be in Mavis's birthing class, didn't show up for the shower. A recent emigrant from London, Tandy has few friends in New York and no family, and she was eagerly looking forward to the party. When Eve finds a gift for Mavis's shower wrapped and ready on the table and a packed bag for the hospital still on the floor, a chill runs down her spine.

Normally, such a case would be turned over to Missing Persons. But Mavis insists that no one else but Eve handle it—and Eve can't say no. She must track Tandy down while simultaneously unearthing the deals and double-crosses hidden in the files of some of the city's richest and most secretive citizens, racing against this particularly vicious killer.

Luckily, her multimillionaire husband Roarke's expertise comes in handy with the number crunching. But as he mines the crucial data to break the case wide open, Eve faces a very real danger in the world of flesh and blood.
