Aldercroft's route into the Intelligence Directorate was not the standard one. She came up through signals interception aboard a border patrol cutter, where the work required less fieldcraft than patience: hours of sifting communications traffic for the one fragment that meant something. She was good at it in the way that some people are good at pattern recognition — not because she worked harder than others, but because she found different things interesting.
The transition to analysis came after she identified a falsified supply manifest that had circulated through Fleet Command undetected for eleven months, concealing a diversion of medical materiel to unlicensed civilian contractors. No action had been taken because no one had connected it to anything. Aldercroft connected it to six other documents and presented the network to Fleet Command in a briefing that took forty minutes and required no questions. The investigation that followed ran for two years.
She has held the directorship for four years. Officers assigned to the Directorate describe a posting where the work is meticulous and the approval, when it comes, is specific: not "well done" but "this section is correct." There are worse things to hear from the person responsible for knowing when something is wrong.
Her caseload extends beyond signals and paperwork. Asset assessment and the review of turned personnel fall under her authority too, work that produces no briefings and appears in no summary, only a signature at the bottom of a file no one else sees.
