The Cradle Robbers

Description for THE CRADLE ROBBERS by Ayelet Waldman:

For private-eye-cum-supermom Juliet Applebaum, business is booming. But there are pros and cons to every assignment. And the con in her latest job is her client, an inmate at Dartmore Prison. She's enlisted Juliet to locate the son she surrendered--as well as the foster parents who've disappeared with him. But this case takes a deadly detour when the desperate young mother is fatally stabbed--allegedly by another inmate.

Prison officials dismiss the murder as just one more fatality in lock-down. But Juliet has her doubts. Now she's determined to make the woman's last wish come true, even if it means tracking little Noah--and the killer--through the dark maze of a widespread conspiracy...

This is #6 in A Mommy-Track Mystery.
