We crowded about Kennedy and the doctor, our eyes riveted on the drawn face before us. Would the antitoxin work?

Meanwhile, Kennedy moved over to the writing-table which he had examined on our first visit to the room. Covered up in the writing-pad was still the paper which he had copied. Only, Mrs. Anthony had added much more to it. He looked at it desperately. What good would it do if, after hours, his cleverness might solve the cipher—too late?

Mrs. Anthony seemed to be struggling bravely. Once I thought she was almost conscious. Glazed though her eyes looked, she saw Kennedy vaguely, with the paper in his hand. Her lips moved. Kennedy bent down, though whether he heard or read her lip movements I do not know.

"Her pocket-book!" he exclaimed.

We found it crushed under her coat which she had taken off when she entered. Craig opened it and drew forth a crumpled sheet of paper from which a corner had been torn. It exactly fitted the scrap that Mrs. Rogers had given us. There, contained within twenty-seven horizontal and twenty-seven vertical lines, making in all six hundred and seventy-six squares, was every possible combination of two letters of the alphabet.

Kennedy looked up, still in desperation. It did him no good. He could have completed the table himself.

"In—the—lining." Her lips managed to frame the words.

Kennedy literally tore the bag apart. There was nothing but a plain white blank card. With a superhuman effort she moved her lips again.

"Smelling-salts," she seemed to say.

I looked about. On the dressing-table stood a little dark-green bottle. I pulled the ground-glass stopper from it and a most pungent odor of carbonate of ammonia filled the room. Quickly I held it under her nose, but she shook her head weakly.
