“What am I to do?” asked the Invisible Man.  “You will get help.  The only thing is for you to go back.”

“I will try.  If he lets me in will you promise not to rush the door?”

“I’ve got no quarrel with you,” said the Voice.

Kemp had hurried upstairs after letting Adye out, and now crouching among the broken glass and peering cautiously over the edge of the study window sill, he saw Adye stand parleying with the Unseen.  “Why doesn’t he fire?” whispered Kemp to himself.  Then the revolver moved a little and the glint of the sunlight flashed in Kemp’s eyes.  He shaded his eyes and tried to see the source of the blinding beam.

“Surely!” he said, “Adye has given up the revolver.”

“Promise not to rush the door,” Adye was saying.  “Don’t push a winning game too far.  Give a man a chance.”

“You go back to the house.  I tell you flatly I will not promise anything.”

Adye’s decision seemed suddenly made.  He turned towards the house, walking slowly with his hands behind him.  Kemp watched him—­puzzled.  The revolver vanished, flashed again into sight, vanished again, and became evident on a closer scrutiny as a little dark object following Adye.  Then things happened very quickly.  Adye leapt backwards, swung around, clutched at this little object, missed it, threw up his hands and fell forward on his face, leaving a little puff of blue in the air.  Kemp did not hear the sound of the shot.  Adye writhed, raised himself on one arm, fell forward, and lay still.

For a space Kemp remained staring at the quiet carelessness of Adye’s attitude.  The afternoon was very hot and still, nothing seemed stirring in all the world save a couple of yellow butterflies chasing each other through the shrubbery between the house and the road gate.  Adye lay on the lawn near the gate.  The blinds of all the villas down the hill-road were drawn, but in one little green summer-house was a white figure, apparently an old man asleep.  Kemp scrutinised the surroundings of the house for a glimpse of the revolver, but it had vanished.  His eyes came back to Adye.  The game was opening well.

Then came a ringing and knocking at the front door, that grew at last tumultuous, but pursuant to Kemp’s instructions the servants had locked themselves into their rooms.  This was followed by a silence.  Kemp sat listening and then began peering cautiously out of the three windows, one after another.  He went to the staircase head and stood listening uneasily.  He armed himself with his bedroom poker, and went to examine the interior fastenings of the ground-floor windows again.  Everything was safe and quiet.  He returned to the belvedere.  Adye lay motionless over the edge of the gravel just as he had fallen.  Coming along the road by the villas were the housemaid and two policemen.

Everything was deadly still.  The three people seemed very slow in approaching.  He wondered what his antagonist was doing.
