At once Burleigh saw what had happened and what it might mean for him.  He had left the hall door open after his visit to the front, and some wandering bird of the night had entered the house.  No need for him to go now.  No need to hide either from the hangman’s rope or the felon’s cell.  The fool above had saved him.  He turned and ran up stairs again just as the prisoner in his furious efforts to escape wrenched the handle from the door.

“Who’s there?” he cried, loudly.

“Let me out!” cried a frantic voice.  “For God’s sake, open the door!  There’s something here.”

“Stay where you are!” shouted Burleigh, sternly.  “Stay where you are!  If you come out, I’ll shoot you like a dog!”

The only response was a smashing blow on the lock of the door.  Burleigh raised his pistol, and aiming at the height of a man’s chest, fired through the panel.

The report and the crashing of the wood made one noise, succeeded by an unearthly stillness, then the noise of a window hastily opened.  Burleigh fled hastily down the stairs, and flinging wide the hall door, shouted loudly for assistance.

It happened that a sergeant and the constable on the beat had just met in the road.  They came toward the house at a run.  Burleigh, with incoherent explanations, ran up stairs before them, and halted outside the library door.  The prisoner was still inside, still trying to demolish the lock of the sturdy oaken door.  Burleigh tried to turn the key, but the lock was too damaged to admit of its moving.  The sergeant drew back, and, shoulder foremost, hurled himself at the door and burst it open.

He stumbled into the room, followed by the constable, and two shafts of light from the lanterns at their belts danced round the room.  A man lurking behind the door made a dash for it, and the next instant the three men were locked together.

Burleigh, standing in the doorway, looked on coldly, reserving himself for the scene which was to follow.  Except for the stumbling of the men and the sharp catch of the prisoner’s breath, there was no noise.  A helmet fell off and bounced and rolled along the floor.  The men fell; there was a sobbing snarl and a sharp click.  A tall figure rose from the floor; the other, on his knees, still held the man down.  The standing figure felt in his pocket, and, striking a match, lit the gas.

The light fell on the flushed face and fair beard of the sergeant.  He was bare-headed, and his hair dishevelled.  Burleigh entered the room and gazed eagerly at the half-insensible man on the floor-a short, thick-set fellow with a white, dirty face and a black moustache.  His lip was cut and bled down his neck.  Burleigh glanced furtively at the table.  The cloth had come off in the struggle, and was now in the place where he had left Fletcher.

“Hot work, sir,” said the sergeant, with a smile.  “It’s fortunate we were handy.”
