Puz has followed a theft suspect all the way to a small-town diner. Across the room sits their detective partner, Milo. Puz needs him to leave at once—but a greeting could spoil the whole investigation.
Two tables. One connection.
Earlier that day, Milo had followed a man in spectacles through the town. After hours of walking, the man stopped at a diner and ordered lunch. Hungry himself, Milo chose a nearby table and ordered noodles, keeping his small notebook on his knee.
Milo’s phone was back at the detective office, charging after its battery had run flat. Puz could not reach him by phone.
Meanwhile, Puz was following a different suspect: a woman in a red scarf. She entered the same diner, paused beside the door, and exchanged a quick look and a nod with the man in spectacles.
Puz stepped inside and picked up a menu. They had not been noticed. The woman sat apart from the man, but her attention kept returning to Milo. When he opened his notebook, she watched his hands.
A warning that cannot be spoken
Puz suspected the two were working together—and that the woman was becoming suspicious of Milo. If Milo kept watching the man, he might reveal himself. The suspects could warn each other, change their plans, or move the stolen goods before police found them.
Milo needed to stop following and leave. But if Puz approached him, called his name, or signaled across the room, the woman might realize they were partners. That would put both detectives’ work at risk.
Then Puz remembered a familiar habit. After a meal, Milo always ordered a cup of warm milk. He had done it at this very diner many times.
Puz walked to the counter, borrowed a pencil, and wrote a few words on a small slip of paper. With one gloved hand covering the writing, they spoke quietly to the waiter beside the clean cups. Then Puz returned to their own table.
Milo changes his plans
Milo finished his noodles and ordered his usual milk. The waiter brought it in a solid cream-colored cup with a green rim. “Your warm milk,” he said, and went away. He did not whisper anything else.
Milo took a sip. As he lifted the cup again, a finger beneath its base paused. He drew his fingertip lightly across the outside bottom, then briefly lowered his hands below the table.
A moment later, Milo finished his drink, closed his notebook, paid, and left without looking toward Puz. The woman watched him go, then turned her attention back to the man in spectacles.
Puz stayed seated with the menu. The suspects no longer seemed worried about Milo. Later, the detectives’ report helped police trace the stolen goods. But one small question remained: how had Milo received the warning?
