As the light slowly died, their figures merged again with the darkness of the trees.

The black-clad figure merged with the darkness of the side alley.

The tall figure glided across the street and merged with darkness.

The figure crossed the street and merged with the darkness that surrounded the house.

Then the tall figure moved away and merged with the darkness beyond the curtain.

The figure flitted toward them and merged with the wall of a building, not more than a dozen feet away.

Even when the figures merged and went down together he felt no alarm.

The blackened figure merged with the solid darkness of the room.

The shadowy figures merged with the black form of the tree.

Then two figures emerged out of the mist and, just as suddenly, merged back into it.
