" We never lock our doors." This is an often-heard remark expressing a commonplace American attitude or belief that, despite whatever danger might prevail in public spaces, life inside our own homes remains (or at least should remain) safe, carefree, normal.

This book covers 13 high-profile cases in which evil paid an untimely visit and found the entrance open--when everything was normal, until it wasn't. Cases include Tommy Lynn Sells, Joshua Komisarjevsky and Steven J. Hayes, Polly Klaas, Richard Ramirez, Richard Trenton Chase, Danny Rollings and others.
