Hanaud rose to his feet and handed the shoes back to the officer.
"Yes," he said, "so it seems. The shoemaker can help us here. I see the shoes were made in Aix."
Besnard looked at the name stamped in gold letters upon the lining of the shoes.
"I will have inquiries made," he said.
Hanaud nodded, took a measure from his pocket and measured the ground between the window and the first footstep, and between the first footstep and the other two.
"How tall is Mlle. Celie?" he asked, and he addressed the question to Wethermill.

"About five feet seven," he answered.
Hanaud replaced his measure in his pocket. He turned with a grave face to Wethermill.
"I warned you fairly, didn’t I?" he said.
Wethermill’s white face twitched.
