"You see this window ?"--he indicated one directly over their heads.

"At exactly one o'clock, when everybody is flocking to the supper tables on the terraces, I expect some one to lean out of that window and talk to some one who will be waiting just below.

There may be no talk, but I think there will be, and I want you to listen to every word of it without so much as drawing a long breath, no matter what is said, until I grab your elbow--like this--then I want you to put up your hand in a hurry while I'm also attendin' to business.
"That's all I'll say now.

But by the time a few words have been said, later, I guess you'll be on.
"Now, we must resign ourselves to a long wait without a smoke and to keeping perfectly still.

I dared not risk comin' any later for fear the others might be beforehand, too." Ruyler ground his teeth.
