"But this time," I pointed out, "you weren't leaving the house—you were returning to it."
"Is that any of your business?" she asked, her eyes beginning to gleam.
"Perhaps not," I admitted.
"And yet you're capable of making a mystery out of it!" she sneered. "Let me relieve your mind—I'm staying with Mrs. Lawrence. She sleeps badly, and wishes me near her."
"And your exits and entrances are, I suppose, usually by the window?"
"It's the most convenient way."
"Mrs. Lawrence doesn't object, then, to your leaving it open?"
"I don't leave it open."
"You did just now."
She looked at me a moment without replying, then laughed a short, little laugh of mingled amusement and vexation.
