"Is there anybody there?" said the caller, "Six ten eight oh one two four three nine?" And his ears attuned to the empty hum Of the long-forgotten line; And an LED on the handset Flashed, for a moment, red, And he dialled the number a second time: "Is there anybody there?" he said. But no one replied to the caller, No sound but the dialling tone Came drifting into his waiting ear As he held that haunted phone; But only a host of phantom listeners, Of spectres weak and strange Stood hearkening to that human voice That echoed around the exchange; And he felt in his heart their strangeness, And his heart was afraid and nervous, With his hand on the final digit Of that number not in service; For he suddenly tapped the receiver And spoke on that line of dread: "Tell them I called, and no one answered, That I kept my word!" he said; Ay, they heard him replace the receiver, And his mumbled cursing later, With the usual subdued but enthused delight Of the switchboard operator.
