I stopped in the middle of the steps, watching his lithe form glide upward.
When the limousine reached Manhattan, that amazing form would glide forth into darkness.
Two minutes later, a phantom form glided from the side exit.
There was a rustle of fabric, and then a tall, dark form glided into the opening.
The stealthy form of The Shadow glided across the space.
It was through this that a black form glided.
The tall form glided across the floor and merged with the gloom of the hall.
His tall thin form glided along the inner hall, until it reached the entrance to the lawyer's office.
Then The Shadow's form glided from the library and back along the passage to the front door.
The tall form glided across the carpeted floor and reached the closed door.
