Von Blon sighed. "I've told you, Ada, that you mustn't take your mother's tantrums too seriously. Her irritability and complaining are part of her disease."
We bade the girl good-by, and the doctor walked with us into the hall.
"I'm afraid you didn't learn much," he remarked, almost apologetically. "It's most unfortunate Ada didn't get a look at her assailant." He addressed himself to Heath. "Did you, by the way, look in the dining-room wall-safe to make sure nothing was missing? You know, there's one there behind the big niello over the mantel."
"One of the first places we inspected." The Sergeant's voice was a bit disdainful. "And that reminds me, doc: I want to send a man up in the morning to look for finger-prints in Miss Ada's room."
Von Blon agreed amiably, and held out his hand to Markham.
"And if there's any way I can be of service to you or the police," he added pleasantly, "please call on me. I'll be only too glad to help. I don't see just what I can do, but one never knows."
Markham thanked him, and we descended to the lower hall. Sproot was waiting to help us with our coats, and a moment later we were in the District Attorney's car ploughing our way through the snow-drifts.
