The boy who land spoken to him earlier stood contemplating him with contemptuous and flashing eyes, and quietly placed the file in the left breast pocket of his coat.

“So, Mr. Sharp, by nature as well as by name,” he said, “it seems that I was right in waiting behind the door in order to see you safely out.  You will appreciate the pleasure I feel in having done so when I tell you my name is Harris.  My mother owns the land on which you have filed, and if there is any justice in Texas she shall hold it.  I am not certain, but I think I saw you place a paper in this file this afternoon, and it is barely possible that it may be of value to me.  I was also impressed with the idea that you desired to remove it again, but had not the opportunity.  Anyway, I shall keep it until to-morrow and let the Commissioner decide.”

Far back among Mr. Sharp’s ancestors there must have been some of the old berserker blood, for his caution, his presence of mind left him, and left him possessed of a blind, devilish, unreasoning rage that showed itself in a moment in the white glitter of his eye.

“Give me that file, boy,” he said, thickly, holding out his hand.

“I am no such fool, Mr. Sharp,” said the youth.  “This file shall be laid before the Commissioner to-morrow for examination.  If he finds—­Help!  Help!”

Sharp was upon him like a tiger and bore him to the floor.  The boy was strong and vigorous, but the suddenness of the attack gave him no chance to resist.  He struggled up again to his feet, but it was an animal, with blazing eyes and cruel-looking teeth that fought him, instead of a man.

Mr. Sharp, a man of high standing and good report, was battling for his reputation.

Presently there was a dull sound, and another, and still one more, and a blade flashing white and then red, and Edward Harris dropped down like some stuffed effigy of a man, that boys make for sport, with his limbs all crumpled and lax, on the stone floor of the Land Office.

The old watchman was deaf, and heard nothing.

The little dog barked at the foot of the stairs until his master made him come into his room.

Sharp stood there for several minutes holding in his hand his bloody clasp knife, listening to the cooing of the pigeons on the roof, and the loud ticking of the clock above the receiver’s desk.

A map rustled on the wall and his blood turned to ice; a rat ran across some strewn papers, and his scalp prickled, and he could scarcely moisten his dry lips with his tongue.

Between the file room and the draftsman’s room there is a door that opens on a small dark spiral stairway that winds from the lower floor to the ceiling at the top of the house.

This stairway was not used then, nor is it now.

It is unnecessary, inconvenient, dusty, and dark as night, and was a blunder of the architect who designed the building.

This stairway ends above at the tent-shaped space between the roof and the joists.
