he little secretary was almost incoherent with fear and anger. The five men, forming a wedge, hurled themselves forward. Out of the White House entrance appeared a tall officer, revolver in hand. It was Colonel Simpson, of the President's staff. Half beside himself, he swept the weapon menacingly about him, shouting incoherently, and clearing a passage, into which the five hurled themselves.

Stopford seized his revolver hand, and after a brief struggle Simpson recognized him.

"He's in the building!" he shouted wildly. "Somewhere upstairs! I'm trying to form a cordon, but this damned mob's in the way. Kick those civilians out!" he cried to the soldiers. "Shoot them if they don't go! Guard the windows!"

Stopford and Dick, at the head of the wedge, pushed past into the White House. The interior was packed, men were struggling frantically on the staircase; it seemed hopeless to try to do anything.

Suddenly renewed yells sounded from above, a scream of anguish, howls of terror. There came a downward surge, then a forward and upward one, which carried the two men up the stairs and into the President's private apartments above.

In the large reception-room a mob was struggling at a window, beneath a blaze of electric light. A soldier was standing there like a statue, his face fixed with a leer of horror. In his hands was a rifle, with a blood-stained bayonet, dripping upon the hardwood floor at the edge of the rug. Upon the rug itself a stream of blood was spouting out of the air.

Dick looked at the sight and choked. There was something appalling in the sight: it was the quintessence of horror, that widening pool of blood, staining the rug, and flowing from an invisible body that writhed and twisted, while moans of anguish came from unseen lips.

Colonel Stopford leaped back, livid and staring. "God, it's got eyes—two eyes!" he shouted.

Dick saw them too. The eyes, which alone were visible, were about six inches from the floor, and they were appearing and disappearing, as they opened and shut alternately. It was a man lying there, a dying man, pierced by the soldier's bayonet by pure accident, dying and yet invisible.
