Marks and Lip. One is a former Marine, the other is a former NSA cyber specialist. They know how to take down a target. You fix eyes on it, hit it, and exploit the site to find your next target. You proceed that way until you eventually take down the entire structure. Doing the "consultant" gig now, they're still tracking down threats. But this threat is a doozy. A mysterious threat, known as Client 487, is intent on planting seeds of dissent that will dismantle our very way of life. The more Marks and Lip discover, the more they realize this has been going on for some time. And it's ugly.
All credit cards have stopped working. Today. This morning. What cash you have in your wallet is it. ATMs and bank systems are down. You can't get gas, or groceries. Commerce has essentially come to a halt. Such is the backdrop of The Back Door Man. Our society is computer centric. Facebook, Twitter, LinkedIn. We're plugged in. Managing our finances online. Downloading apps for our iPhone. Reading the WSJ on our Kindle. There are things out there on the cutting edge we don't even know we need to fear. The Back Door Man takes us there.
