"I should like to see the young King," I replied, truthfully enough, indeed. "But I can't manage to dine with you. Give me the number of your box, and if I can get my work done I'll try and join you there. I must be off now, in fact."

"You seem to be very hard-worked at the Embassy," she replied.

"This is not purely Embassy work; it's rather extra-official than otherwise."

"A.B.C. used to say that when a man had out-of-office work there was generally a woman in the case."

"Ah, he was an American; and American customs are very unpopular in Madrid just now;" and as my time was up, I hurried away. A short drive carried me to the stables where my horse was in waiting ready saddled, and not a vestige of the little farce remained in my thoughts as I mounted and rode slowly off on what might be so momentous an errand for me.

I knew the city well enough to pick my way through by-streets till I reached the outskirts and came out on to the Aravaca road, and then I rattled on for a mile to put my horse's powers to the test. He was a splendid animal, and in the pink of condition, very fast, as sure-footed as a mule, and wonderfully obedient alike to voice, knee, and rein. He would have made a magnificent hunter, and when I put him across a bit of country he took as much pleasure in it as I myself. A jewel of a horse for the task I was upon.

I reached the spot I had chosen for my hiding place well before the time; and, tethering my horse securely, I climbed a tree which was to be my observation post, and commenced my vigil. I had about half an hour to wait, for my ride had taken less time than I had allowed; but there was not much fear of the time dragging.

I had with me a pair of folding field-glasses of great power and range, and with these I swept the country round for indications of the approach of the royal carriage or of any Carlist preparations. For a long time I looked in vain; but presently a carriage, drawn by a pair of stalwart horses, appeared about half a mile away to my left on the road from the city. It was travelling rapidly, and I lost it soon afterwards behind a small olive wood, which stood close to the crest of the hill. As it did not appear again, the deduction was easy that it was the Carlist carriage, and had been drawn up in concealment to wait for the coming of the young King. I would have given a great deal to know the number of those in it—but this was, of course, impossible.

Five minutes later four horsemen straggled up one by one, with considerable intervals between them, and as they did not show on my side of the little wood, I set them down as a further instalment of the performers in the coming drama.

As there must be now at least six or eight men, the number of them gave me a twinge of uneasiness. If anything like that number of men were going with the young King after he had been put in the Carlist vehicle, I had made a very grave miscalculation in my plans, which might have the most serious consequences.
