The beam of a searchlight came now, across the water.

The twin beams of light had come from his own eyes!

The beam comes from the lower left in this diagram.

Look to your left, where those two beams come together.

The man in black was simply dropping back each time a beam of light came his way.

The beams were coming from two dozen different directions at once.

In fact, Kirk could see that the beam had not even come close.

Then the beam came back to his face and he chuckled.

But that was suddenly all right: he knew now where the beams were coming from.

Her eyes locked on the spot where she thought the beam had come from.
