Riley had spent enough years in federal service to trust the quiet instinct that told him something was wrong—the same instinct that had once flagged a forged signature buried inside a stack of otherwise ordinary documents. He found himself glancing back over his shoulder twice more before he reached the front doors.
There was a particular stillness in the way the man in the cell had been sitting: spine straight, hands folded, eyes fixed calmly on some middle distance, reminding Riley of officers he had once briefed early in his own career—men who carried themselves as though every room they entered was still, in some small way, a command post. He told himself it was probably nothing, a coincidence born of a long day and an overactive imagination, but the feeling lingered all the same.
Riley hesitated, his instincts telling him that something did not add up, but he had a schedule to keep and no formal authority in that particular case, so he continued down the hallway to deliver his paperwork, promising himself he would ask more questions if the opportunity arose again.
Meanwhile, in the small office at the rear of the building, Captain Dillon stood staring at his own computer screen, having personally attempted to override the fingerprint lockout, only to receive the same red warning that had stopped Coleman twice already. He rubbed the back of his neck, told himself it was nothing more than an aging system overdue for replacement, and ordered that Marcus remain in custody until someone from the county office could come by in the morning to sort out the paperwork properly.
By early evening, Marcus asked once more for his telephone call. This time, worn down by the accumulating strangeness of the afternoon, Captain Dillon reluctantly agreed, if only to prove to himself that nothing would come of it.
He led Marcus to a small phone in the hallway and stood close by, arms crossed, expecting to hear a rambling excuse or a call to some relative who would beg for his release.
Instead, Marcus dialed a number he clearly knew by memory, waited three rings, and spoke six words in a tone that was suddenly sharper and more precise than anything the officers had heard from him all day. He identified himself by name and rank, then recited a short sequence of letters and numbers, calling it authentication code "Delta Seven," before falling silent and listening.
On the other end of the line, a young operator at a secure desk hundreds of miles away froze at the sound of that code, immediately placing the call on hold and alerting a duty officer without explanation.
