“I shall be glad when this is over,” said Frank to himself. “How long that woman is. The girl may be dead before morning and we none the wiser for what she knows!” He tried to catch a sentence here and there of her wanderings, but it told him nothing beyond the fact that her brother was somehow mixed up in the affair, and her one anxiety was for his safety.

At length, after what seemed to Frank an hour’s waiting, but which in reality was but half the time, footsteps stopped outside in the silent street. In a few moments two figures entered the room and a brisk sharp voice exclaimed, “A light, Miss Kempe, and quickly; do you suppose I can attend a patient in the dark?” Then Miss Kempe groped in the depths of a corner cupboard, and presently produced a small end of a small candle ensconced in a large flat candlestick; this Frank quickly lighted with one of his cigar matches, and exchanging greetings with the doctor, turned with him towards the bed.

The doctor held the candle low, throwing the light on the girl’s face, then he shook his head. “Are you afraid of infection?” he said, turning to Frank, “if so you had better go home at once.”

“Afraid!” repeated Varley, “No, I am not afraid of anything under heaven when I have an object in view. But what is it? What is she suffering from?”

“Suppressed small-pox. A very bad case; something on her mind, too, I should say,” this with a keen glance at Frank, “Twenty-four hours will see the end of it.” Then he turned to Miss Kempe and proceeded to give her some necessary directions.

And twenty-four hours did see the end of it. About an hour before midnight, Frank was joined in his watch by Detective Hill, who at once offered to take sole charge of the case. “No,” said Frank decisively, “as long as there is the shadow of a chance of the shadow of a clue being given I shall remain. Your ears are sharpened by your practice and profession, but mine, Mr. Hill, by something with which your profession has nothing to do.”

“Gentlemen,” said the doctor, as the grey dawn began to struggle through the narrow panes, and light up the poorly furnished room. “It is perfectly useless for either of you to remain. The delirium has ceased, and the girl has fallen into a state of stupor from which she will never waken. She will never speak again.”

Still they stayed on. The Detective, as the day wore away, went in and out for his meals or a breath of fresh air, for the small room had become stifling. But Frank never stirred. “She may die at any moment,” he thought, “and it’s just possible that at the very last her energies may re-kindle, and she may make some sign that will need interpretation.”

So he waited and waited. The doctor came in and out, attending neighbouring patients and returning at intervals. The old clock went tick, tick, in the corner, and Miss Kempe, on her knees at the bedside, prayed audibly for the poor dying one. “Will you not join me, sir,” she had said to Frank, “in wrestling for this poor sinner’s soul?”

“I won’t say I won’t join you, Miss Kempe,” Frank had replied, “but you must let me stay here by the window.”
