And this was the manner of his going. He sought the Sergeant upon his balcony, outside which climbed and writhed a great old vine-stem as thick as a man's leg. He was for taking Killiecrankie by his side, against the Sergeant's advice.

"Killiecrankie and I," he urged, with the buckle in his hand, "have been in many frays together, and I have never known him fail me yet."

"A sword like a weaver's beam is monstrously unhandy dangling between the legs!" replied the Sergeant, "and that you will find before you are at the foot of yonder vine-stock. Take a pair of pistols and a good Albacete leech. That is my advice. I think I heard El Sarria say that you had some skill of knife-play in the Andalusian manner."

"So, so," returned Rollo, modestly. "I should not like to face you—your left hand to my right. But with most other men I might make bold to hold my own."

"Good!" said the Sergeant; "now listen. Let yourself down, hand-grip by hand-grip, clipping the vine-stem as best you may with your knees to make the less noise. You will be wholly hidden by the outer leaves. Move slowly, and remember I am here to keep watch and ward. Then stand a while in the shadow to recover your breath, and when you hear me whistle thrice like a swallow's twitter underneath the eaves, duck down as low as you can and make straight for the thickest of the underbrush over there. I have watched it for an hour and have seen nothing move. Yet that signifies less than nothing. There may be a score, aye, or a hundred gipsies underneath the branches, and the frogs croaking undisturbed upon the twigs above all the while. Yet it is your only chance. If you find anything there in shape of man, strike and cry aloud, both with all your might, and in a moment I will be with you, even as I was before."

Rollo grasped the Sergeant's hand and thanked him silently as brave men thank one another at such times.

"Nay," said the Sergeant, "let us wait till we return for that. It is touch and go at the best. But I will stay here till you are safely among the bushes. And then—I shall have some certain words to speak to Señor Don Fernando Muñoz, Duke of Rianzares and grandee of Spain, Consort in ordinary to her Majesty the Queen-Regent!"

Even as he spoke, Rollo, whose ears were acute, turned quickly and dashed into the ante-chamber. He thought he had heard a footstep behind them as they talked. And at the name of Muñoz a suspicion crossed him that some further treachery was meditated. But the little upper hall was vague and empty, the scanty furniture scarce sufficient to stumble against. If any one had been there, he had melted like a ghost, for neither Rollo's swift decision nor the Sergeant's omniscient cunning could discover any trace of an intruder.

Rollo attempted no disguise upon his adventure. He wore the same travel-stained suit, made to fit his slender figure by one of the most honest tailors in Madrid, in which he first appeared in this history. So with no more extent of preparation for his adventure than settling his sombrero a little more firmly upon his head and hitching his waist-belt a hole or two tighter, Rollo slipped over the edge of the iron balcony and began to descend by the great twisted vine-stem.

He did not find the task a difficult one. For he was light and agile, firmed by continuous exercise, and an adept at the climbing art. As he had been, indeed, ever since, on the east-windy braes of Fife, where swarming rookeries crown the great hog-back ridges, he had risen painfully through the clamour of anxious parents to possess himself of a hatful of speckled bluish-green eggs for the collection wherewith he was to win the tricksome and skittish heart of Mistress Peggy Ramsay, who (tell it not in the ducal house which her charms now adorn!) was herself no inexpert tree-climber in the days when Rollo Blair temporarily broke his boyish heart for her sake.
