Miriam Giles ran away to Colorado to bury her violent past - but this seductive, charismatic widow had a dark side that could never stay buried. After finding the "sugar daddy" she was looking for in Alan Helmick, her new marriage seemed happy. Then, two years later, Alan met a gruesome fate. Returning home from errands, Miriam found him lying in a pool of blood. Miriam showed police a cryptic note warning her to "run, run, run." But Miriam was no distraught housewife. She was a master manipulator always able to stay one step ahead of her unwitting partner - and the law - until now.
