There he waited - and from his invisible lips came the laugh of The Shadow!

A pale tongue slid from between thin nearly invisible lips.

The March winds drowned the whispered laugh that came from invisible lips.

A soft, whispered laugh sounded from invisible lips beneath the hat brim.

Long hands drew on thin black gloves; a whispered laugh sounded from invisible lips.

Similarly, only an acute ear could have caught the whispered mirth that came from invisible lips.

And only now did he make invisible lips with which to do it, pushing an unseen tongue into her mouth.

The nearly invisible lips parted to gasp, in words like puffs of smoke.

As it shifted away, a whispered laugh throbbed from invisible lips.

The Shadow stood above him, the suppressed sound of taunting mirth coming from his invisible lips.
