"Very well," he said, "I shall go to Bois d'Avril at once——"
"It is not necessary; I have a message for you, and some papers from Mr. Gray."
"Really?"
The young man smiled, drew from his inner pocket a long, thin envelope, and handed it to Halkett. The latter held it in his hand, looking steadily into the stranger's pleasant face for a full minute, then he coolly opened the envelope.
Inside were the missing papers concerning the Harkness shell, complete.
There could be no doubt concerning their identity; he recognized them at a glance. A deep sigh of relief escaped him.
He said:
"There's no use trying to thank you——"
"It's quite all right," interrupted the young man smilingly. "If you don't mind offering me a drink—the road over was rather dusty——"
"Leave your wheel there and come in!" exclaimed Halkett cordially, stepping aside in the doorway.
