"I'm quite alone," she assured him softly. "Can you throw it in?"
He nodded.
"I think so."
His first effort was successful. The seal followed, wrapped up in his handkerchief. A moment or two later he saw Pamela's face at the window.
"Good night!" she whispered. "Quickly, please. There is still some one about downstairs."
The light was extinguished. Lutchester made his way cautiously back, replaced the gate upon its hinges and reached the shelter of the Embassy, denuded now of guests. He found Downing in the smoking-room.
"Can I get a whisky and soda?" Lutchester asked, in response to the latter's vociferous greeting.
"Call it a highball," was the prompt reply, "and you can have as many as you like. Have you earned it?" he added, a little curiously.
"I almost believe that I have," Lutchester assented.
