“The maid hung one out to dry,” Dr. Stone said.
“Why, yes.” Harley Kent stopped short. “That’s it,” he added, and was gone. Presently he was back. “Not there. I suppose it will turn up some place. Well, come in; come in. The police should be here before long.”
They mounted to the porch and Lady, after the manner of her breed when trained to work with the blind, stopped with her head directly under the knob of the strange door.
“A remarkable animal,” Harley Kent said in admiration. “Well, here’s where the job was done, Doctor.”
Joe was conscious of strange tremors. Lady, alert, cocked her head and sniffed the air with an inquiring nose. The doctor, halting in the arched doorway leading from the hall, seemed to lose himself in thought.
“There’s a door to the left of this room, Kent?”
“Yes; it leads into the dining room.”
“And windows in the wall facing this way. They’re open now.”
Harley Kent gave a startled grunt. “Doctor, if I didn’t know you were blind——”
“Air currents,” Dr. Stone said laconically. “I feel them on my face. You feel them, too, but they go unnoticed. You rely on your eyes. The wall safe, then, should be in the solid wall on the right. Correct, Kent?”
