Our intrepid Agents were called into a briefing at 0900 on Tuesday, July 4th. AIC Blake began her mission prep with a video surveillance feed that showed an individual that everyone viewing the video perceived as themselves and another male, with long greasy-looking hair and a bandana covering his face entering the lobby of a bank after hours. They then watched "themselves languidly squeeze off a shot at a security guard (clearly not bothering to aim) that scored a perfect head shot. The second individual, when surprised by a second guard, slapped him with a long strip of paper, causing him to vanish. The two then went down to the vault, opened it in record time, and proceeded to load cash into bags they'd brought with them, before fleeing the scene.
After the video, Blake handed out dossiers on the two items used by the perpetrators. She explained that the slip of paper had been known of for 20+ years, and that it always sent people to the bottom of the mule train trail in the Grand Canyon (the paper itself was a receipt for the trail). The gun was older, had been known for over 60 years. It never missed, and it would hide the wielder from cameras by projecting false images (usually that of whoever was viewing the video). Both items had been in the possession of the Aegis (and other services) on and off over the years, but they always seemed to slip back into the public.
The agents boarded a flight soon after, and arrived at the bank in the guise of FBI agents who were investigating this robbery because it matched the MO of several others around the country. Several hours were spent collecting evidence, eventually identifying the auto the robbers had likely arrived and departed in, tracking it to a reported stolen car several weeks before.
As they approached the residence it had been stolen from, they saw another government issued black SUV leaving the area. Running it's plates, it turned out to be a local FBI fleet vehicle. Interviewing the owner gave them basic information, though Red Harvest and Bastet wound up talking to a young man by the name of Wally, who seemed mute and generally odd. When his behavior was noticed by his parents, they were obviously greatly concerned, and wound up rushing him to the hospital.
Eventually the agents decided to check up on the FBI agents who had preceded them to the house, and discovered that they'd abandoned the car several miles away (and that the agents who had checked out the car were, in fact, off duty that day and at a cookout during the time in question). They eventually tracked these doppelgangers to an office building, where most of the group wound up being hit by a device that left them nearly catatonic (but otherwise unharmed). Bastet did manage to wound one of the perpetrators before succumbing to the device, but the perps had nearly a half hour to make good their escape before Tank & Pygmalion came up to check on their fellow agents.
The office in question proved to be that of Dr. Mattias Nelson, a neurosurgeon who had lost his license to practice medicine but somehow retained his license to practice psychiatry. According to records, he also had advanced degrees in electrical engineering and sociology, One patient in particular from his records stood out, listed only as Jane Doe, who had been fitted with some sort of "device" that was reportedly allowing her to live a normal life free of the seizures she'd previously been afflicted with.
It is also important to note that the agents found a fair sized incendiary bomb (sans detonator) which had been left in the office. Said device could have easily destroyed all the records there, but for some reason the device had never been armed (or, perhaps, had been disarmed by the pair of false agents who had scrambled everyone's brains).
