Aimée Leduc seems to be having a streak of good luck. First, she secures a lucrative computer security contract for her Paris detective agency. Then her exboyfriend Yves, the gorgeous bad-boy investigative journalist, reappears in her life. He insists he's back in Paris indefinitely—and wants to make the ultimate commitment. He proposes to her that very night, and Aimée can't help but say yes.
When she wakes up in the morning, though, Yves is gone, and without even leaving a note. Aimée is irate until she learns the awful truth: Yves was murdered early that morning. Heartbroken and convinced the Brigade Criminelle are not following the right leads, Aimée pursues the mystery behind Yves's murder. Yves was killed trying to help a cause he believed in. Her own life may be on the line, but Aimée won't let him die in vain.
