One Bad Apple

When a virus is unleashed on the Department of Defense’s computers, programmer Marshall “The Worm” Fenwick is certain he’ll be blamed. After all, it’s an act of cyber-vandalism worthy of a man with a history of hacking, a false accusation that Marshall's never been able to live down. Marshall knows he didn’t do it. It had to be someone else at ApplCart, the virus protection company he works for. Marshall can arrest the damage and escape going down for the crime himself if he can find—and find it in time—the One Bad Apple among the company’s employees.
