"Mommy, they found a dead child in the bathroom."
Dr. Hannah Kline has a busy obstetrical practice, an adorable six-year-old and a brand new live-in lover. The last thing she needs in her life is a murder at her daughter Zoe's exclusive private school.
Detective Daniel Ross doesn't make a habit of falling in love with women he meets during murder investigations, but he made an exception for Hannah and now he's adjusting to their new living arrangement. He just wishes that she'd stop putting herself in danger by investigating his cases.
When the dead child turns out to be in Hannah's carpool, and the granddaughter of a good friend, Hannah can't help getting involved. After all, she has the inside track at the Waverly School and Zoe's safety is at stake.
