"Were you not rather rash," I asked of Madame Gilbert, "to give yourself away so completely? He might not have been so thorough an ass as you thought."

"My friend," said Madame calmly, "I had taken tea with him twice, and had satisfied myself that he was not, what you call, very bright. A dear fellow, handsome, a gentleman of the English pattern, but not bright. If I had not helped him to get a move on, I might have lunched with him, had tea, dined with him, attended theatres, traversed in motors your pleasant countryside, flirted, until I had become a very old woman, and there would have been nothing to show for all my exertions. I remembered the instructions of Mr. Dawson, I recalled to myself my duty, I was compelled to discover who and what was this Capitaine Rouille, and I could only succeed by forcing him to reveal himself—to give himself away. When I said that I was an agent of the English police, he did not believe me; but he was curious—he watched me. I gave him much to watch and to imagine that he had discovered. Then one began to get forward."

* * * * *

I am ignorant of the diplomatic pourparlers which led up to the week-end trip to Brighton, that remarkable trip which ended l'affaire Rust. It must have been planned by Madame; it bears the unmistakable imprint of her impish wit; it was, too, a bold development of her designs for the effective speeding up of Rust. He would have dallied all through the summer, looking feebly for an opportunity to ravish a despatch-case which always accompanied Madame and which had become the inseparable and ostentatious "gooseberry" at their meetings. Madame declared that it was stuffed with papers the most secret. "The English Government would be desolated if they passed for one moment out of my hands." This despatch-case played parts quite human. It was perpetually provocative of Rust's curiosity, and a reminder that the agreeable pastime of making love to Madame was not an end in itself, but a means whereby he might discharge his official duties. It was, moreover, a visible sign that Madame was a woman, tres occupee, and a self-styled agent de police; it rested always silent at her side as a protector of innocence. Rust becomes uneasy when that case is mentioned, but Madame bubbles over at the thoughts of her petite chere portefeuille, cette idee de genie. She brags of her genius, of her notion si lumineuse, of her guet-apens si adorable.

While Madame must have planned the Brighton trip, she contrived that the suggestion should come timidly, deprecatingly, from Rust. She would have scorned so crude an advance, one, too, falling so far short of her high standard of womanly virtue, as a direct hint that she was willing to pass three days in a seaside hotel with a young man! Mais, non. Ce serait une betise incroyable! I can imagine her hints, increasing in strength as she beat against the obtuse heaviness of Rust's intellect. But I cannot imagine how any one, least of all the brilliant Froissart, should have conceived that lumpish soldier to be capable of the finesse needful for the Secret Service. He has since been returned empty, and I do not wonder at it.

Madame must have lamented the stuffiness of London during the bright days of early June, and painted, in her enthusiastic French fashion, a picture of southern England and the glittering Channel. "Ma foi, mon ami, what would I not give for one hour of peace and rest, away from this swarming hive of men and women? It is as yet too cold to swim in that sea which washes the shores of my beautiful France—and bears the so gallant English soldiers to her help—but I would love to sit upon the sands and gaze, gaze across the waters towards my poor bleeding land. But, alas, I am a woman tres occupee." After a great deal of this sort of thing, Rust was spurred up to suggest that he also was weary, and that nothing could be more delightful than to sit beside Madame upon those sands and to bewail with her the woes of their common country. The idiot did not reflect that a woman of Madame's taste in dress does not usually mess up her Paris frocks with nasty sea sand. Madame sighed. It was a charming picture, but, alas, quite impossible. Rust still further spurred by Madame—"Le Capitaine Rouille is not very bright"—at last broke into a proposal delivered with many hesitations and many apologies. Why should not they travel to Brighton on the Friday evening and draw solace for their weary souls from a Saturday, Sunday, and possibly Monday, at Brighton? Madame became a frozen statue of offended womanhood! What, mon Dieu, had she done that he should conceive her to be a light woman? She, the never-to-be-comforted widow of the incomparably gallant hero of anthracite stoves and le Grand Couronne. She had been too unsuspicious, too trustful; their pleasant acquaintance must end upon the instant; the too-gross insult which he had put upon her could never be pardoned. Rust was borne away and overwhelmed in the flow of her sad reproaches. Abjectly he grovelled: He regard the ineffable Madame Guilbert as a light woman! Perish the thought! He, to whom she had been an angel of kindness and discretion! He cast a slur upon the shining brightness of her reputation! Rust had never in his life been so eloquent. Madame listened with satisfaction. She might in time, after long years, forgive him, but not yet. The insult, however unintended, was too fresh and her heart was desolated! She scorched and scarified Rust during two whole days, for their meetings continued unbroken, and at last, as an undeserved concession and as evidence of her soft forgiving heart, she consented to go to Brighton on the Friday. "We must regard closely les convenances. You men, so rash and so stupid, you do not understand how infinitely precious to us poor women is the spotless bloom of our reputation." Rust protested that the bloom upon the unplucked peach was not, in his eyes, more stainless than the reputation of Madame. How she must have grinned! He made plans, rude, coarse plans, for the shielding of the so precious reputation of dear Madame Guilbert, but she gently put them aside. "In my hands," she declared grandly, "le Capitaine Guilbert has left his honour, and I will guard it with my life. Alas, what is my life when my heart is buried in that lonely grave upon le Grand Couronne in which I pray rests his much-blown-up body. I myself will devise the means by which I can grant you a mark of my condescending forgiveness and preserve sans reproche the honour of a Guilbert."

I confess that I have drawn upon my imagination for most of this touching scene, but, knowing Madame as I do, I am sure that I have given the hang of it.

CHAPTER XI

AT BRIGHTON

Madame Gilbert and Captain Rust travelled to Brighton on the Friday evening in the Pullman train. They occupied different carriages. Their hotel, one of those facing the sea which washed the far-off shores of their beloved, bleeding France, had been selected by Madame—"I desire a hotel, my friend, not a caravanserai!" Madame arrived ten minutes before Rust, and had disappeared within her own appartement when his cab drove up to the doors. Rust then booked his room, one upon the second floor. He took that which was offered, and did not observe that Madame's room was also au seconde. But he did notice—he could not help it—that the imposing lady in charge of the hotel office was French. "Ah, monsieur le capitaine," said she, beaming caresses upon him, "with what joy do I perceive the tenue de campagne of my own Army. I will gladly grant to you one of the rooms of the very best and at the price of the lowest. The patron, he also is French, and would be furious if I did not give the most cordial welcome to an officier francais." Rust thanked the lady of the bureau, and heartily approved Madame's choice of an hotel.
