The cab having moved on,—

“I regret,” began O’Hagan, “that we have missed our supper! But I have triumphantly proven my words anent the survival of Romance. You note into what a surprising adventure we have blundered merely by honouring a Grand Duke with our company! Here we have all the elements of a stirring romance indeed: the autocratic nobleman, the distressed lovers, the ring as a token! I am delighted, Raymond!”

“O’Hagan!” I interrupted sternly—“if you are delighted, I am appalled! Of the deception practised upon the Duke I will say nothing; but to have tricked a girl who confided——”

“Stop!” cried O’Hagan imperiously. “Stop there, Raymond! You!—my friend—and charge me with such a crime! Raymond!——”

“She thinks,” I interrupted, excitedly——

“She thinks,” my friend took me up, “that we are acquainted with her secrets, and trusts us accordingly. Good. Is her trust misplaced? Do we intend to betray her? No! ten thousand times no! It is perfectly evident that her lover—Christian name, Leo; surname, unknown; nationality, possibly Polish—is involved in some conspiracy directed against a government—probably that of Russia. Her father, or guardian, our mutual acquaintance the Duke, had obtained, through the treachery of one Casimir, proofs of Leo’s complicity. These, we may assume, he intended to employ—(a) to frustrate Leo’s designs in regard to the lady; (b) to bring about the arrest, or ruin, of the said Leo.

“Delightful, my boy! Wildly and picturesquely romantic! Enter Lawrence Raymond and Bernard O’Hagan—and what becomes of the ducal plan? It miserably crumbles to dust! Virtue and Love are triumphant, and we are the heroes of the hour!”

The cab stopped before a dingy little café. Our entire capital O’Hagan lavished upon the man, and we entered the café.

Its front portion proved to consist of a shop where coffee-pots and such utensils were sold, and behind the counter sat an adipose and unctuous lady of considerable maturity. O’Hagan’s entrance brought her to her feet in quick alarm.

My friend held the ring before her eyes. She viewed it in palpable wonder, her slightly crooked gaze vacillating betwixt the face of my cavalierly friend and my own.
