It was a swinging door of green baize and he pushed it open a cautious
inch.

"See anything?"

For answer Rose drew in his breath sharply.

"Doggone! Here's some liquor I'll say!"

"Liquor?"

Key joined Rose at the door, and looked eagerly.

"I'll tell the world that's liquor," he said, after a moment of
concentrated gazing.

It was a room about twice as large as the one they were in--and in it
was prepared a radiant feast of spirits. There were long walls of
alternating bottles set along two white covered tables; whiskey, gin,
brandy, French and Italian vermouths, and orange juice, not to mention
an array of syphons and two great empty punch bowls. The room was as
yet uninhabited.

"It's for this dance they're just starting," whispered Key; "hear the
violins playin'? Say, boy, I wouldn't mind havin' a dance."

They closed the door softly and exchanged a glance of mutual
comprehension. There was no need of feeling each other out.
