Argyll laughed. “Good-night, then,” said he, “and a riddance to your vapours before the morning's morning.”

Mrs. Petullo had begun a song before the Duke entered, a melody of the Scots mode, wedded to words that at that period hummed round the country. It was the one triumphant moment of her life—her musically vocal—when she seemed, even to the discriminating who dive for character below the mere skin, to be a perfect angel. Pathos, regret, faith, hope, and love, she could simulate marvellously: the last was all that was really hers, and even that was lawless. She had not half-finished the air when the Duke came into the room softly on his tiptoes, humming her refrain. A keen ear might have perceived the slightest of alterations in the tone of her next stanza; a quick eye might have noticed a shade of disappointment come to her face when her intent but momentary glance at the door revealed that some one she sought was not entering. The only ear that heard, the only eye that saw, was Kilkerran's. He was a moralist by repute, and he would have suspected without reasons. When Mrs. Petullo broke down miserably—in her third verse, he smiled to himself pawkily, went up to her with a compliment, and confirmed his suspicions by her first question, which was as to the Chamberlain's absence.

As for the Chamberlain, he was by now hurrying with great speed through the castle garden. Only once he slacked his pace, and that was when the garden path joined the more open policies of the Duke, and another step or two would place a thicket of laburnums and hawthorns between him and the sight of the litten windows. He hung on his heel and looked back for a minute or two at the castle, looming blackly in the darkness against the background of Dunchuach; he could hear the broken stanza of Mrs. Petullo's ballad.

“Amn't I the damned fool?” said he half-aloud to himself with bitter certainty in the utterance. “There's my punishment: by something sham—and I ken it's sham too—I must go through life beguiled from right and content. Here's what was to be the close of my folly, and Sim MacTaggart eager to be a good man if he got anything like a chance, but never the chance for poor Sim MacTaggart!”

He plunged into the darkness of the road that led to the Maltland barracks where the fifty claymores were quartered.

CHAPTER XI — THE WOMAN AT THE WINDOW

Count Victor heard the woman's lamentation die away in the pit of the stair before he ceased to wonder at the sound and had fully realised the unpleasantness of his own incarceration. It was the cries of the outer assault that roused him from mere amazement to a comprehension of the dangers involved in his being thus penned in a cell and his enemies kept at bay by some wooden bars and a wooden-head. He felt with questioning fingers along the walls, finding no crevice to suggest outer air till he reached the window, and, alas! an escape from a window at that height seemed out of the question without some machinery at hand.

“I suspected the little clown's laughter,” said he to himself. “The key of the mystery lies between him and this absurd Baron, and I begin to guess at something of complicity on the part of M. Bethune. A malediction on the whole tribe of mountaineers! The thing's like a play; I've seen far more improbable circumstances in a book. I am shot at in a country reputed to be well-governed even to monotony; a sombre host puzzles, a far too frank domestic perplexes; magic flutes and midnight voices haunt this infernal hold; the conventional lady of the drama is kept in the background with great care, and just when I am on the point of meeting her, the perplexing servitor becomes my jailer. But yes, it is a play; surely it is a play; or else I am in bed in Cammercy suffering from one of old Jeanne's heavy late suppers. It is then that I must waken myself into the little room with the pink hangings.”

He raised the point of the sword to prick his finger, more in a humorous mood than with any real belief that it was all a dream, and dropped it fast as he felt a gummy liquor clotting on the blade.
