And unlike the little girl, he understood immediately that this was no ordinary recognition scene.

“What do you mean, the wrong half?” he asked.

The elderly woman didn’t answer him. She was staring at the open locket as if it had become dangerous just by being opened in daylight.

The little girl held it tighter.

“My mommy said if I saw the ring, I should open it and not let anybody take it,” she whispered.

That made the woman go pale.

The man stepped closer, carefully, like people do around frightened animals and hidden weapons.

“Can I see the picture?” he asked.

The child hesitated. Then slowly held the locket out.

Inside, the faded image showed a younger version of the woman near a hospital bed. But something was wrong with it. The photo had been cut — neatly, precisely. One side was missing.

The man looked up.

The woman’s hand moved instinctively to her coat pocket.

He noticed.

So did the child.

“What’s in your pocket?” he asked.

The woman didn’t answer.

The little girl’s crying had softened now into that terrifying quiet children fall into when they feel the adults around them know something they do not.

“My mommy said if the lady was scared,” the child whispered, “that means she remembers.”

The woman finally spoke.

“She should never have sent you here alone.”

The man’s expression hardened. “You know her mother.”

The woman gave a tiny nod.

“Where is she?” he asked.

But before she could answer, the little girl said, “She told me not to say.”

The man crouched to her level. “Why?”

The child looked at the photograph, then at the ring.

“Because the man who watches the ring,” she said, “still looks for us.”

A chill passed through all three of them.

The man straightened slowly.

The woman closed her eyes for one second, then reached into her coat and pulled out something small wrapped in a handkerchief.

When she opened it, the man felt his stomach drop.

It was the missing half of the photograph.

The two halves matched perfectly.

But now the full image showed what had been hidden before:

the young woman in the hospital bed was not alone.

Standing just behind her, partly cut out on purpose, was a man with one hand on the bedrail.

And on his little finger was a ring with the exact same stone as the elderly woman’s.

The child stared.

The woman’s voice shook.

“If your mother told you to run,” she said, “then he already knows she found me.”

The man looked up sharply. “Who?”

The elderly woman turned toward the street.

A black car had just stopped across the road.

And in the dark rear window, someone was already watching the bench.
