Suddenly the house was full of the Invisible Man's resounding blows on the kitchen door. The girl stared towards the kitchen, shuddered, and retreated into the dining-room. Kemp tried to explain in broken sentences. They heard the kitchen door give.

"This way," said Kemp, starting into activity, and bundled the policemen into the dining-room doorway.

"Poker," said Kemp, and rushed to the fender. He handed the poker he had carried to the policeman and the dining-room one to the other. He suddenly flung himself backward.

"Whup!" said one policeman, ducked, and caught the axe on his poker. The pistol snapped its penultimate shot and ripped a valuable Sidney Cooper. The second policeman brought his poker down on the little weapon, as one might knock down a wasp, and sent it rattling to the floor.

At the first clash the girl screamed, stood screaming for a moment by the fireplace, and then ran to open the shutters--possibly with an idea of escaping by the shattered window.

The axe receded into the passage, and fell to a position about two feet from the ground. They could hear the Invisible Man breathing. "Stand away, you two," he said. "I want that man Kemp."

"We want you," said the first policeman, making a quick step forward and wiping with his poker at the Voice. The Invisible Man must have started back, and he blundered into the umbrella stand.

Then, as the policeman staggered with the swing of the blow he had aimed, the Invisible Man countered with the axe, the helmet crumpled like paper, and the blow sent the man spinning to the floor at the head of the kitchen stairs. But the second policeman, aiming behind the axe with his poker, hit something soft that snapped. There was a sharp exclamation of pain and then the axe fell to the ground. The policeman wiped again at vacancy and hit nothing; he put his foot on the axe, and struck again. Then he stood, poker clubbed, listening intent for the slightest movement.

He heard the dining-room window open, and a quick rush of feet within. His companion rolled over and sat up, with the blood running down between his eye and ear. "Where is he?" asked the man on the floor.

"Don't know. I've hit him. He's standing somewhere in the hall. Unless he's slipped past you. Doctor Kemp--sir."

Pause.

"Doctor Kemp," cried the policeman again.

The second policeman began struggling to his feet. He stood up. Suddenly the faint pad of bare feet on the kitchen stairs could be heard. "Yap!" cried the first policeman, and incontinently flung his poker. It smashed a little gas bracket.

He made as if he would pursue the Invisible Man downstairs. Then he thought better of it and stepped into the dining-room.

"Doctor Kemp--" he began, and stopped short.

"Doctor Kemp's a hero," he said, as his companion looked over his shoulder.

The dining-room window was wide open, and neither housemaid nor Kemp was to be seen.

The second policeman's opinion of Kemp was terse and vivid.
