Then—"How did you guess?" Cecelia Brooke asked in wonder.

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…."
