So, with one of Dr. Mason’s cameras under the seat, we started back through the sweet-smelling lanes; and, at about twenty minutes past one, swung past the gate lodge and up the long avenue, the wheels grinding crisply upon the newly wetted gravel. There was but little moon, now, and the house stood up, an irregular black mass, before us.

Then, from three of the windows, there suddenly leapt out a dazzling white light!

Lorian pulled up the grey with a jerk.

“Good God!” he said. “What’s that! An explosion!”

But no sound reached us. Only, for some seconds, the hard, white glare streamed out upon the steps and down on to the drive. Suddenly as it had come—it was gone, and the whole of Ragstaff was in darkness as before!

The horse started nervously, but my friend held him with a firm hand, turning and looking at me queerly.

“That’s what shone under your door last night!” he said. “That light was in the hall!”

Peters was awakened, the horse stabled and ourselves admitted without arousing another soul. As we came around from the back of the house (we had not entered by the main door), and, candles in hand, passed through the hall, nothing showed as having been disturbed.
