up. He had been stooping over the table. The fog was creeping
into the room. And in the uncertain light about the ceiling he missed
the gold piece and it fell on the table before Sir Henry. The gold piece
did not ring, it fell dull and heavy, and the big Baronet looked at it
openmouthed as though it had suddenly materialized out of the yellow fog
entering the room.

"My word!" he cried. "One of the nine hundred horses!"

Hargrave stopped motionless like a man stricken by some sorcery.

"One of the nine hundred horses!" he echoed.

The Baronet was digging at the gold piece with the blade of his knife.

It was a fairy night, and the thing was a fairy story.

The sun had merely gone behind a colored window. The whole vault of the
heaven was white with stars. The road was like a ribbon winding through
the hills. In little whispers, in the dark places, Marion told me it.
We sat together in the tonneau of the motor. It was past midnight, of
a heavenly September. We were coming in from a stately dinner at the
Fanshaws'.

A fairy story is a nice, comfortable human affair. It's about a hero,
and a thing no man could do, and a princess and a dragon. It tells
how the hero found the task that was too big for other men, how he
