“Of course,” he nodded.  And they retraced their steps together.

He left her at the door of the quaint, one-storied stone building where, she explained, she had a cot.

“You will come to see me again before you go back to your regiment, won’t you?” she pleaded, keeping one hand in both of hers.

“Of course I will.  Try to get some sleep, Letty.  You’re tremendously pretty when you’ve had plenty of sleep.”

They both laughed; then she went indoors and he turned away across the road, under the windows of the ward where Ailsa was on duty, and so around to his store-room dwelling-place, where he sat down on the cot amid the piles of boxes and drew from his pocket the crumpled sheets of the letter that Ailsa had given him.

The handwriting seemed vaguely familiar to him; he glanced curiously down the page; his eyes became riveted; he reddened to the roots of his hair; then he deliberately began at the beginning, reading very carefully.

The letter had been written several weeks ago; it was dated, and signed with Hallam’s name: 

“MY DEAR MRS. PAIGE: 

“Only my solemn sense of duty to all pure womanhood enables me to indite these lines to you; and, by so doing, to invite, nay, to encourage a cruel misunderstanding of my sincerest motives.

“But my letter is not dictated by malice or inspired by the natural chagrin which animates a man of spirit when he reflects upon the undeserved humiliation which he has endured from her who was once dearer to him than life itself.  Mine is a nature susceptible and sensitive, yet, I natter myself, incapable of harbouring sentiments unworthy of a gentleman and a soldier.

“To forgive, to condone, is always commendable in man; but, madam, there is a higher duty men owe to womanhood—­to chaste and trusting womanhood, incapable of defending itself from the wiles and schemes which ever are waiting to ensnare it.

“It is for this reason, and for this reason alone, that, my suspicions fully aroused, I have been at some pains to verify them.  A heart conscious of its moral rectitude does not flinch from the duty before it or from the pain which, unfortunately, the execution of that duty so often inflicts upon the innocent.

“Believe me, dear Mrs. Paige, it is a sad task that lies before me.  Woman is frail and weak by nature.  Man’s noblest aspiration can attain no loftier consummation than in the protection of a pure woman against contamination.

“Mine becomes the unhappy mission of unmasking two unworthy people whom you, in your innocence and trust, have cherished close to your heart.  I speak of the trooper Ormond—­whose name I believe you know is Philip Berkley—­and, if you now hear it for the first time, it is proof additional of his deceit and perfidy.

“The other is Miss Lynden, known, in a certain immoral resort called the Canterbury, as Letty Lynden, or ‘Daisy’ Lynden.
