"Do so!" he suggested.

I crossed the room, and, drawing the blind aside carefully, looked out. The street was packed with people! Even as I stood there, I heard the crash of breaking glass below!

"What does it mean?" I asked, bewildered.

"Your Rifle Corps, I should think," Staunton said, without ceasing writing. "We closed the doors just in time. They will try to wreck the place."

"We have telephoned to Scotland Yard and the Horse Guards," the man who stood by my side said, "and we have forty policemen inside the place now! Good God!"

The sudden roar of an explosion split the air. The floor seemed to heave under our feet, and the windows fell in with a crash, letting in the cold night air. We could hear distinctly now the shrieks and groans from below. It seemed to me that the roadway was suddenly strewn with the bodies of prostrate men. I sprang back into the room, we all looked at one another in horror. I think that for my part I expected to see the walls close in upon us.

"A bomb," Staunton remarked calmly. "Listen!"

He leaned a little forward in his chair, his pen still in his hand, his attitude one of strained and nervous attention. By degrees the tension in his face relaxed.

"It goes!" he muttered. "Good!"

He bent once more over his work. I looked at the man by my side in bewilderment.
