A DOUBLE ASSIGNATION I followed Leon upstairs to the region of smaller apartments.

At the door of one of these he knocked, and a feminine voice at once bade us enter.
Mademoiselle was sitting upon a lounge, smoking a cigarette.

On the table before her stood an empty coffee-cup and an empty liqueur-glass.

She looked at me with a little grimace.
"At last!" she exclaimed.
"It is the gentleman whom mademoiselle was expecting ?" Leon asked discreetly.
"Certainly," she answered.

"You may go, Leon." We were alone.
