Discountenanced by the admiration glowing in her eyes, Lanyard stood fumbling with the disjointed members of Blensop's pen.

"Do not give me too much credit," he depreciated: "anybody acquainted with that roll of paper could have guessed that an empty fountain pen would furnish an ideal place of concealment for it. Moreover, just before you came in, that traitor missed his pen, and his consternation betrayed him beyond more doubt to one whose distrust was already astir. As for the other, it was true: Blensop did write down the combination on this pad, using a pencil with a hard lead; the marks are very plain."

"But for whose use?"

"Ekstrom--Anderson--was here last night, and saw Blensop alone. Colonel Stanistreet was not at home. Knowing what we know now, that Blensop was a creature of the German system here, bought body, soul, and conscience through its studied pandering to his vices, we know he could not well have refused to surrender the combination on demand."

"Still I fail to understand...."

"Ekstrom, being Ekstrom, could not resist the opportunity to play double.

Here was a property he could sell to England at a stiff price. Why not despoil the enemy, put the money in pocket, then return, steal the paper anew for the use of Germany, and collect the stipulated reward from that source? But he reckoned without Blensop's avarice, there; he showed Blensop too plainly the way to profit through betraying both parties to a bargain; Blensop saw no reason why he should not play the game that Ekstrom played.

So he stole it for himself, to sell to Germany, but being a poor, witless fool, lacking Ekstrom's dash and audacity, was foredoomed to failure and exposure."

The girl continued to eye him steadfastly, and he as steadfastly to evade her direct gaze.

"Nothing that you tell me detracts from the wonder of your guessing so accurately," she insisted. "Now I know what Mr. Crane said of you was true, that you are one of the most extraordinary of men."

"He was too kind when he said that," Lanyard protested wretchedly. "It is not true. If you must know...."

"Well, Monsieur Lanyard?"

Her tone was that of a light-hearted girl, arch with provocation. Of a sudden Lanyard understood that he might no longer stop here alone with her.

"If you will be a little indulgent with me," he suggested, "I will try to explain what I mean."

"And how indulgent, monsieur?"

"I have a whim to take the air in this garden. Will you accompany me?"

"Why not?"

As she led the way through the French windows, he noted with deeper misgivings how her action matched the temper of her voice, how she seemed to-day more deliciously alive and happier than any common mortal.

So light her heart! And all since she had found him here!

At his wits' ends, he conceded now what he had so long denied. With all her wit and wisdom, with all her charm of beauty, winsomeness, and breeding, with all her ingrained love of truth and honesty, she was no more than Nature had meant her to be, a woman with woman's weakness for the man she must admire. She liked him, divined in him latent qualities somehow excellent. Something in him worked upon her imagination, something, no doubt, in the overcoloured, romantic yarns current about the Lone Wolf, and so had touched her heart. She liked him too well already, and she was willing to like him better.

But that must never be. He must rend ruthlessly apart this illusion of romance with which she chose to transfigure the prowling parasite of night, the sneaking thief....

The garden was sweet with the bright promise of Spring. A few weeks more, and its formal walks would wend a riot of flowers. Now its sunlight made amends for what it lacked in beauty of growing things; and its air was warm and fragrant and still in the shelter of the red-brick walls.

Midway down that walk, by the side of which a thief had skulked nine hours ago, near that door whose lock had yielded to his cunning keys, the girl paused and confronted Lanyard spiritedly as he came up with heavy step and hang-dog head.

"Well, monsieur?" she demanded. "Do you mean to tantalize me longer with your reticence?"

But something in the haggard eyes he showed her made the girl catch her breath.

"What is it?" she cried anxiously. "Monsieur d.u.c.h.emin, what is your trouble?"

"Only this truth that I must tell you," he said bitterly: "I merely played a part back there, just now. There was neither wit nor guess-work in that business; once I had seen Blensop's panic over the fancied loss of his pen, the rest was knowledge. I saw him and Ekstrom together last night--skulking in those windows, I watched them; and though in my denseness I didn't understand, I saw him write upon that pad, tear off and give the sheet to Ekstrom. And I knew Ekstrom had not succeeded in stealing back what he had sold to Colonel Stanistreet, knew he was guiltless in fact if not in deed."

"But--how could you know that?"

"Because I was there, in the room, when he entered it after it had been shut up for the night."

Conscious of her hands that fluttered like wounded things to her bosom, he looked away in misery.

"What were you doing there?" she whispered in the end.

"Trying to find that paper, which I had seen Ekstrom sell to Colonel Stanistreet, so that I might make good my promise and relieve your distress by returning it to you. I had opened the safe before he entered, and searched it thoroughly, and knew the paper was not there--though at that time it never entered my thick head to suspect Blensop of treachery. It was neither Blensop nor Ekstrom, Miss Brooke ... it was I who stole that necklace."

She made no sound and did not stir; and though he dared not look he knew her stricken gaze was steadfast to his face.

"I will say this much in my defence: I did not come with intent to steal, but only to take back what had been stolen from me, and return it to you, who had trusted it to my care. I wanted to do that, because I did not then understand the ins and outs of this intrigue, and had no means of knowing how deeply your honour might be involved."

"But you did _not_ take that necklace!"

"I am sorry.... I saw it, and could not resist it."

"But Mr. Crane a.s.sured me you had given up all that sort of thing years ago!"

"Notwithstanding that, it seems I may not be trusted...."

After another trying silence she declared vehemently: "I do not believe you! You say this thing for some secret purpose of your own. For some reason I can't understand you wish to abase yourself in my sight, to make me think you capable of such infamy. Why--ah, monsieur!--why must you do this?"

"Because it isn't fair to represent myself as what I am not, mademoiselle.

Once a thief, always--"

"No! It isn't true!"

"Again I am sorry, but I know. You have been most generous to believe in me. If anything could save me from myself, it would be your confidence.

That, I presume, is why I felt called upon to undo my thieving, and make good the loss. The money Colonel Stanistreet paid Ekstrom is now in the safe, back there in the library. The necklace is ... here."

Blindly he thrust the tissue packet into her hands.

"If you will consent to return it to its owner, when I have gone, I shall be most grateful."

Her hands shook so that, when she would open the packet, it escaped her grasp and dropped into a little pool of rain-water which had collected in a hollow of the walk. Lanyard picked it up, stripped off the soiled and sodden paper, dried the necklace with his handkerchief, replaced it in her hand.

He heard the deep intake of her breath as she recognized its beauty, then her quavering voice: "You give this back because of me...!"

"Because I cannot be an ingrate. I know no other way to prove how I have prized your faith in me.... And now, with your leave, I will go away quietly by this garden gate--"

"No--please, no!"

"But--"

"I have more to say to you. It isn't fair of you to go like this, when I--"
