Day One. Partridge in a pear tree: During the night-shift at the NSA, Booz Allen contractors suddenly have their online Christmas shopping interrupted when Booz Allen proprietary counterterrorist data-mining algorithms note an unusual spike in internet chatter of “persons of interest” using the term “partridge in a pear tree.” Their NSA Contracting Officer’s Technical Rep is alerted.
Day Two. Two turtle doves: At the NSA, SAIC contractors discover a correlation between “partridge in a pear tree” and “two turtle doves.” The NSA notifies the CIA. CIA analysts who are new to the job due to high Agency turnover do not recognize the turtle-dove/partridge-in-a-pear-tree pattern, but speculate that the combination of phrases indicates that a terrorist plan may have gone operational. The White House is briefed.
