Blue Ant Series by William Gibson

Cayce Pollard is an expensive, spookily intuitive market-research consultant. In London on a job, she is offered a secret assignment: to investigate some intriguing snippets of video that have been appearing on the Internet. An entire subculture of people is obsessed with these bits of footage, and anybody who can create that kind of brand loyalty would be a gold mine for Cayce's client... moreCayce Pollard is an expensive, spookily intuitive market-research consultant. In London on a job, she is offered a secret assignment: to investigate some intriguing snippets of video that have been appearing on the Internet. An entire subculture of people is obsessed with these bits of footage, and anybody who can create that kind of brand loyalty would be a gold mine for Cayce's client. But when her borrowed apartment is burgled and her computer hacked, she realizes there's more to this project than she had expected.Still, Cayce is her father's daughter, and the danger makes her stubborn. Win Pollard, ex-security expert, probably ex-CIA, took a taxi in the direction of the World Trade Center on September 11 one year ago, and is presumed dead. Win taught Cayce a bit about the way agents work. She is still numb at his loss, and, as much for him as for any other reason, she refuses to give up this newly weird job, which will take her to Tokyo and on to Russia. With help and betrayal from equally unlikely quarters, Cayce will follow the trail of the mysterious film to its source, and in the process will learn something about her father's life and death. less

Tito is in his early twenties. Born in Cuba, he speaks fluent Russian, lives in one room in a NoLita warehouse, and does delicate jobs involving information transfer. Hollis Henry is an investigative journalist, on assignment from a magazine called Node. Node doesn't exist yet, which is fine; she's used to that. But it seems to be actively blocking the kind of buzz that magazines normally cultivate before they start up. Really actively blocking it... moreTito is in his early twenties. Born in Cuba, he speaks fluent Russian, lives in one room in a NoLita warehouse, and does delicate jobs involving information transfer. Hollis Henry is an investigative journalist, on assignment from a magazine called Node. Node doesn't exist yet, which is fine; she's used to that. But it seems to be actively blocking the kind of buzz that magazines normally cultivate before they start up. Really actively blocking it. It's odd, even a little scary, if Hollis lets herself think about it much. Which she doesn't; she can't afford to. Milgrim is a junkie. A high-end junkie, hooked on prescription antianxiety drugs. Milgrim figures he wouldn't survive twenty-four hours if Brown, the mystery man who saved him from a misunderstanding with his dealer, ever stopped supplying those little bubble packs. What exactly Brown is up to Milgrim can't say, but it seems to be military in nature. At least, Milgrim's very nuanced Russian would seem to be a big part of it, as would breaking into locked rooms. Bobby Chombo is a "producer", and an enigma. In his day job, Bobby is a troubleshooter for manufacturers of military navigation equipment. He refuses to sleep in the same place twice. He meets no one. Hollis Henry has been told to find him. less

Milgrim can disappear in almost any setting, and his Russian is perfectly idiomatic—so much so that he spoke it with his therapist in the secret Swiss clinic where Bigend paid for him to be cured of his addiction... Garreth doesn't owe Bigend a thing... moreHollis Henry never intended to work for global marketing magnate Hubertus Bigend again.
