Audrey enlarged the photograph.
Martin’s briefcase appeared ordinary at first.
Dark leather.
Brass locks.
A scratch near the lower corner.
Then she noticed the thin black cable emerging from one side and disappearing beneath his coat.
The phone vibrated again.
SIGNAL REPEATER.
Audrey’s mind moved quickly.
A repeater could capture or boost nearby communications.
It could intercept devices.
Copy transmissions.
Perhaps activate something.
“Diana,” Audrey called.
“Yes?”
“Move away from Martin.”
“What?”
“His briefcase. There is a cable running from it under his coat.”
Outside, shoes scraped against the floor.
Martin’s voice rose.
“This has gone far enough.”
A sharp electronic tone sounded.
Then every light in Audrey’s room went out.
The fetal monitor went dark.
The steady beat of her son’s heart vanished.
