3rd Tango — Adrienne Giordano

Growing up, the Schock sisters lived across the street from a serial killer--at least according to their mother. She's spent years spying on the man and tracking his every move, but no concrete evidence has ever been found.

When Helen Schock joins a citizens cold case group and uncovers a link between her suspicious neighbor and three murdered women found in Virginia fifteen years ago, she does the one thing Meg and Charlie never expect...she hires them to prove she's been right all along.

As the three work together to expose the truth and bring justice to the dead, they uncover an unexpected twist to the case...and find themselves hunted by a killer desperate enough to destroy them all.
