My 7-year-old grandson leaned toward me and whispered: “Grandpa, when you leave for Dallas, Mommy and Daddy are going to keep all your money,” and in that instant, I understood why my daughter was so insistent on knowing the exact time of my flight; what she didn’t know was that, behind a simple signature, there was something capable of snatching away much more than my savings.

It wasn’t a gesture of doubt. It was worse. It was the calculated movement of someone who remembers an important detail just in time. She turned her head slightly, just enough for me to see the hard glint in her eyes.
