“Nothing more for tonight, thank God,” he thought with relief.
He closed and fastened the windows, bolted the door, and was passing into his bedroom, when the telephone rang.
“Damn! Why didn’t I muffle it?”
He put the receiver to his ear.
“Well?” he said abruptly.
“Doctor Carlson speaking?”
“Yes.”
“Can you come at once to a very sick case?”
“I’m sorry, but I can’t. My car is out of order, and I’m not very well myself tonight.”
“But this case is extremely urgent, sir, and we don’t want anyone else but you.”
