Sam Fisher- Spigot

  FISHER’S pistol had in fact four dart settings: one through three, and then level four, which was yet another bit of magic from the shadowed halls and devious minds at DARPA. Fisher had read the scientific name for the dart’s contents once and its tongue-torturing complexity made him glad they’d given it a code name, Spigot, which, he assumed was meant to describe what the chemical did to a person’s short-term memory—namely, it opened a notional valve on his or her brain and let twenty to thirty minutes of short-term memory leak out.

  There are two kinds of memory, short-term and long-term; the former stored by the frontal and parietal lobes, the latter stored weblike throughout different portions of the brain. The bridge between the two, the part of the brain that converts short-term memory into long-term memory, is governed by the hippocampus, which is where Spigot worked its magic. By partially dissolving the chemical glue that holds the hippocampus bridge together, Spigot created a mild version of retrograde amnesia that turned the target’s previous thirty minutes of memory into dreamlike recollections that faded within minutes of regaining consciousness.

  So, despite his first instinct, the truth was, Fisher had had no intention of killing Legard. As much as the man deserved to be gone from the planet—and Fisher was giving serious thought to paying him another visit after all this was over—his death would stir up a hornet’s nest of trouble, especially if he was in contact with whoever he’d delivered Carmen Hayes to and to whoever was about to deliver his latest prisoner, the man Legard had identified as Calvin Stewart.

  If Fisher was going to follow the trail of clues that appeared to have gotten Peter killed, he needed this pipeline to remain open. Of course, Fisher was painfully aware that by maintaining the pipeline’s integrity, he was allowing Legard to send who knew how many kidnapped girls to their overseas buyers. Another time, Fisher thought, another late-night visit.

  In quick order, he hit Legard with a level three dart and a level four, then unbound him. He did the same to Bruno, then returned the training dummy to its stand and turned the lights back on. While both men would awake confused, neither would remember anything of the last half hour. Legard was fencing; Bruno watching. And then . . . nothing until they awoke. And if Fisher did his job right, leaving no trace of his presence, and nothing was found missing or out of place following the inevitable security sweep Legard would order, their minds would find a way to write off the experience.
