Would a brother-agent take her in his arms, then reprove her with every symptom of vexation for her "madness," her "insanity," her "nonsense" that was like to "drive me mad"?—Thackeray's own words!

Vainly Lanyard cudgelled his wits for some plausible reading of this riddle.

Was this Brooke girl possibly (of a sudden he sat bolt upright) a Prussian agent infatuated with this young Englishman and by him beloved in spite of all that forbade their passion?

Did not this explanation reconcile every apparent inconsistency in her conduct, even to the entrusting to a stranger of the stolen secret, the purloined paper she dared not keep about her lest it be found in her possession?

Lanyard's eyes narrowed. Visibly his features hardened. If this surmise of his were any way justified in the outcome, he promised Miss Cecelia Brooke an hour of most painful penitence.

Woman or not, she need not look for mercy from him, who must ever be merciless in his dealings with Ekstrom's crew.

To be made that one's tool!

The very thought was intolerable….

As for himself, possession of this paper meant that pitfalls were digged for his every step.

If ever the British found cause to suspect him, his certain portion would be to face a firing squad in dusk of early day.
