"P.S.—We might call at Lady Portlebury's lawn, and look over the conservatories."

"Now, that's bold, but judicious," Ernest said to himself, admiringly, as he held the letter at arm's-length, after blotting it. "She might have been angry at my inviting myself, though I don't think she would be; but I'm sure she'll be only too delighted if I offer to take her guests over Aunt Portlebury's conservatories. The postscript's a stroke of genius. What a fuss these people will make, even over the widow of a stupid old cavalry officer, because her husband happens to have been knighted. It's all the better that she's a widow, indeed. The delicious vagueness of the title 'Lady' is certainly one of its chief recommendations. Sir Antony being out of the way, Mrs. Montagu's guests can't really tell but that poor dear old Aunt Portlebury may be a real live Countess." And he folded his second letter up with the full satisfaction of an approving conscience.

When Isabel Walters received Ernest Carnegie's mysterious note, she was certainly mystified by it as he had expected, and also not a little gratified. He meant to propose to her, that was certain; and there was never a woman in the whole world who was not flattered by a handsome young man's marked attentions. It was a very queer letter, no doubt; but it had been written skilfully enough to suit the particular personality of Isabel Walters: for Ernest Carnegie was a keen judge of character, and he flattered himself that he knew how to adapt his correspondence to the particular temperament of the persons he happened to be addressing. And though Isabel had no very distinct idea of what the two Carnegies were severally like (it could hardly have been much more distinct if she had known them both intimately), she felt they were two very good-looking, agreeable young men, and she was not particularly averse to the attentions of either. After all, upon what straws we all usually hang our love-making! We see one another once or twice under exceptionally deceptive circumstances; we are struck at first sight with something that attracts us on either side; we find the attraction is mutual; we flounder at once into a declaration of undying attachment; we get married, and on the whole we generally find we were right after all, in spite of our precipitancy, and we live happily ever afterwards. So it was not really very surprising that Isabel Walters, getting such a note from one of the two handsome young Mr. Carnegies, should have been in some doubt which of the two identicals it actually was, and yet should have felt indefinitely pleased and flattered at the implied attention. Which was Ernest and which Harold could only mean to her, when she came to think on it, which was the one she danced with first last night, and which the one she danced with second. She decided in her own mind that it would be better for her to go to the Montagus' picnic to-morrow, but to say nothing about it to her mother. "Mamma wouldn't understand the letter," she said to herself complacently; "she's so conventional; and when I come back to-morrow I can tell her one of the young Carnegies was there, and that he proposed to me. She need never know there was any appointment."

IV.

At six o'clock, Harold Carnegie returned from the office. He, too, had been thinking all day of Isabel Walters, and the moment he got home he went into the library to write a short note to her, before Ernest had, as usual, forestalled him. As he did so he happened to see a few words dimly transferred to the paper in the blotting-book. They were in Ernest's handwriting, and he was quite sure the four first words read, "My dear Miss Walters." Then Ernest had already been beforehand with him, after all! But not by a fortnight: that was one good point; not this time by a fortnight! He would be even with him yet; he would catch up this anticipatory twin-brother of his, by force or fraud, rather than let him steal away Isabel Walters from him once and for ever. "All's fair in love and war," he muttered to himself, taking up the blotting-book carefully, and tearing out the tell-tale leaf in a furtive fashion. "Thank Heaven, Ernest writes a thick black hand, the same as I do; and I shall probably be able to read it by holding it up to the light." In his own soul Harold Carnegie loathed himself for such an act of petty meanness; but he did it; with love and jealousy goading him on, and the fear of his own twin-brother stinging him madly, he did it; remorsefully and shamefacedly, but still did it.

He took the page up to his own bedroom, and held it up to the window-pane. Blurred and indistinct, the words nevertheless came out legibly in patches here and there, so that with a little patient deciphering Harold could spell out the sense of both letters, though they crossed one another obliquely at a slight angle. "Very brief and casual acquaintance ... Montagus' steam-launch expedition up the river from Surbiton to-morrow ... am going and am particularly anxious to meet you ... this favour of you...." "So that's his plan, is it?" Harold said to himself. "Softly, softly, Mr. Ernest, I think I can checkmate you! What's this in the one to Mrs. Montagu? 'Expect me to turn up at half-past two.' Aha, I thought so! Checkmate, Mr. Ernest, checkmate: a scholar's mate for you! He'll be at the hospital till half-past one; then he'll take the train to Clapham Junction, expecting to catch the South-Western at 2.10. But to-morrow's the first of the month; the new time-tables come into force; I've got one and looked it out already. The South-Western now leaves at 2.4, three minutes before Mr. Ernest's train arrives at Clapham Junction. I have him now, I have him now, depend upon it. I'll go down instead of him. I'll get the party under way at once. I'll monopolize Isabel, pretty Isabel. I'll find my opportunity at Aunt Portlebury's, and Ernest won't get down to Surbiton till the 2.50 train. Then he'll find his bird flown already. Aha! that'll make him angry. Checkmate, my young friend, checkmate. You said it should be war, and war you shall have it. I thank thee, friend, for teaching me that word. Rivals now, you said; yes, rivals. 'Dolus an virtus, quis in hoste requirat?' Why, that comes out of the passage about Androgeos! An omen, a good omen. There's nothing like war for quickening the intelligence. I haven't looked at a Virgil since I was in the sixth form; and yet the line comes back to me now, after five years, as pat as the Catechism."

Chuckling to himself at the fraud to stifle conscience (for he had a conscience), Harold Carnegie dressed hastily for dinner, and went down quickly in a state of feverish excitement. Dinner passed off grimly enough. He knew Ernest had written to Isabel; and Ernest guessed from the other's excited, triumphant manner (though he tried hard to dissemble the note of triumph in it) that Harold must have written too—perhaps forestalling him by a direct proposal. In a dim way Mrs. Carnegie guessed vaguely that some coldness had arisen between her two boys, the first time for many years; and so she held her peace for the most part, or talked in asides to Nellie Holt and her daughter. The conversation was therefore chiefly delegated to Mr. Carnegie himself, who discoursed with much animation about the iniquitous nature of the new act for reducing costs in actions for the recovery of small debts—a subject calculated to arouse the keenest interest in the minds of Nellie and Edie.

Next morning, Harold Carnegie started for the office with prospective victory elate in his very step, and yet with the consciousness of his own mean action grinding him down to the pavement as he walked along it. What a dirty, petty, dishonourable subterfuge! and still he would go through with it. What a self-degrading bit of treachery! and yet he would carry it out. "Pater," he said, as he walked along, "I mean to take a holiday this afternoon. I'm going to the Montagus' water-party."

"Very inconvenient, Harold, my boy; 'Wilkins versus the Great Northern Railway Company' coming on for hearing; and, besides, Ernest's going there too. They won't want a pair of you, will they?"

"Can't help it, Pater," Harold answered. "I have particular business at Surbiton, much more important to me than 'Wilkins versus the Great Northern Railway Company.'"
