"Prevent things being stolen," Grayle answered.
"Nobody's stolen anything yet,—and we've been here a week! But, if anybody did steal, it would probably mean that he wanted it more than we did."

"But who d'you keep it open for?" I asked.
He shrugged his shoulders and laughed.
"Your friend, the doctor, his patient, that lady who came in a moment ago. You, if you will come again."
