Mrs. Chalmers broke off in the middle of a sentence to flap her gauntlet gloves at a swarm of persistent flies. “All the same, I think it’s perfectly disgraceful that you are still a bachelor, Micky,” she said, with emphatic cousinly candour, resuming an argument which had raged for the last half hour. Major Meredith grinned with perfect good humour.

“Haven’t time for matrimony,” he answered lazily, “too busy watching our wily brothers over the Border. And besides,” with a provocative sidelong glance, “marriage is a lottery. We can’t all expect to have Bill’s luck.”

Mrs. Chalmers wrinkled her nose at him disgustedly. “That’s a cliché,” she said with fine scorn, ignoring the implied compliment, “it merely means that you haven’t yet met the right woman. However—” she laughed mischievously—“there’s still hope for you. A year at home after nearly ten years of exile will probably make you change your mind. It’s a pity you didn’t take your leave sooner, there were some charming girls here last winter. Unfortunately this year’s sample is not recommendable, there is scarcely a really nice girl in the place—always excepting Marny Geradine, and she’s married already—poor child.”

“Why ‘poor child?’ ” asked the soldier, his cousin’s sudden change of tone seeming to call for some comment. “Because—” Mrs. Chalmers paused frowningly, “oh, well, you haven’t seen Lord Geradine or you wouldn’t ask,” she went on soberly, “he’s been away on a shooting trip since you’ve been here—and the air of Algiers has been consequently cleaner,” she added with a little shiver.

Major Meredith hoisted his long limbs up into a sitting position. “A case of a misfit marriage?” he suggested.

“Marriage!” echoed Mrs. Chalmers scornfully, “it isn’t a marriage, it’s a crime. It makes my blood boil to think of it. And yet I hardly know them. He’s impossible, and she is the shyest, most reserved young woman I have ever met. I’d give a great deal to be able to help her, she seems so lonely and there is tragedy staring at you out of her eyes. But of course one can’t do anything. She isn’t the kind of person who makes confidants. I’ve blundered in pretty often during my life when it hasn’t been my business, but I simply shouldn’t dare to speak to Lady Geradine of her affairs—though I am old enough to be her mother. Ugh! let’s talk of something less revolting,” she said hastily, a trace of huskiness in her voice. And for a time she sat silent, staring absently in front of her with eyes that had become very wistful and tender. Then with a shrug and a half sigh she turned again eagerly to her companion. “There is a great deal that wants putting right in the world, Micky,” she said with ungrammatical decisiveness, “but I’m not going to spoil a perfect afternoon by moralising. It has been jolly, hasn’t it? I thought you would like this little valley. So few people seem to know of it, no special inducement to bring them here except peace and quietness which most of the folk wintering in Algiers don’t seem particularly to hanker after. We found it years ago and have camped here often, a haven of refuge when life was especially strenuous or perplexing. It is sad to think that it is our last visit and that in a few weeks we shall have shaken the dust of Algeria off our feet. Five years, Micky, five years that Bill has been marking time in this Back of Beyond because of my stupid lungs. But they are all right now, thank God, and we are off to America as soon as may be to investigate some new nerve treatment Bill is interested in. And when he has picked the brains of his transatlantic confrères we shall come home to end our days in Harley Street in an odour of sanctity and general stuffiness. Won’t London be simply horrid after years of fresh air and open spaces? So, you see, you only just caught us in time. If your leave had been delayed you would have missed us, and I did want you to see our Algerian home. It’s been a hectic fortnight, but I’ve enjoyed every minute of it, and I think we’ve managed to show you all the sights of Algiers and its immediate surroundings. But I do regret one thing—I wish you could have seen our Mystery-man. He is quite a feature of the place. An Englishman who lives like an Arab—you needn’t pull a face, Micky, I don’t mean that he has ‘gone native’ or anything horrid of that kind, he is much too dignified. But he lives in a sort of splendid isolation in the loveliest villa in Mustapha, with a retinue like a Chief’s. And though he is tremendously popular with the French officers and all the important Sheiks who come into Algiers he pointedly avoids his fellow countrymen. And he won’t speak to or even look at a woman! He wears Arab dress most of the time and would pass for a native anywhere. He lives for months together in the desert and descends on Algiers at irregular intervals. One hears that he is in the town, and glimpses him occasionally stalking along with his head in the air rather like a supercilious camel, or riding like a hurricane through the streets in approved Arab style, but that is all that the English community ever see of him. And he has obviously heaps of money—and it’s a gorgeous villa. He might be such an acquisition to the place, but, as it is, he is merely an intriguing personality who is ‘wropt in mystery,’ as old Nannie used to say. Needless to add that in a place like this, where we all discuss our neighbours, he is the subject of endless speculation. But nobody really knows anything about him.”

A faint chuckle came from behind Doctor Chalmers’ big helmet. “I’m sorry to contradict you, Mollie, but that is not strictly accurate,” he said sleepily. His wife sat up with a jerk. “Who knows?” she challenged.

“Well—I do, for one,” replied Doctor Chalmers coolly.

“You know, Bill—and you’ve never said. How like a man! Really, you are the most exasperating creatures on earth. Fancy having that pearl of information up your sleeve—I’m getting mixed up in my metaphors, but never mind—and withholding it from the partner of your joys and sorrows. I shouldn’t have passed it on if it was a confidence, you know that very well. But since you have admitted so much you can soothe my outraged feelings by imparting a little more.”

Doctor Chalmers laughed and stretched lazily. “Can’t be done,” he replied succinctly.
