"Listen!" he cried. "Again!"

"What?" asked Kate.

"I hear them, I tell you."

Her lips blanched, and parted to speak, but she checked the impulse and
looked swiftly about the room with what seemed to Byrne an appeal for
help. As for Buck Daniels, he changed from a dark bronze to an unhealthy
yellow; fear, plain and grimly unmistakable, was in his face. Then he
strode to the window and threw it open with a crash. The wind leaped in
and tossed the flame in the throat of the chimney, so that great shadows
waved suddenly through the room, and made the chairs seem afloat. Even
the people were suddenly unreal. And the rush of the storm gave Byrne an
eerie sensation of being blown through infinite space. For a moment
there was only the sound of the gale and the flapping of a loose picture
against the wall, and the rattling of a newspaper. Then he heard it.

First it was a single note which he could not place. It was music, and
yet it was discordant, and it had the effect of a blast of icy wind.

Once he had been in Egypt and had stood in a corridor of Cheops'
pyramid. The torch had been blown out in the hand of his guide. From
somewhere in the black depths before them came a laugh, made unhuman by
echoes. And Byrne had visioned the mummied dead pushing back the granite
lids of their sarcophagi and sitting upright.

But that was nothing compared with this. Not half so wild or strange.
