"Who accompanied you besides the child?"
"François—the chauffeur."
"Always?"
"Yes."
Duvall turned to Mrs. Stapleton. "How long has this man François been in your employ?"
"A year—in June."
"You have found him honest, reliable?"
"Always. Otherwise I should not have kept him."
The detective turned to Mary Lanahan. "Go ahead, please," he said.
"We reached the Bois shortly before eleven—François had orders to go slowly, when Master Jack was in the machine—and drove about for fifteen minutes. Then we stopped at the place where we were in the habit of playing."
