“Spiffing!” said Miss Penny.  “If Mr. Pixley gets on our track we’ll play hide-and-seek in them with him.”

“Then we ought to spend a day on Brecqhou—­”

“A day on Brecqhou without a doubt!”

“And if we can get the boat from Guernsey to call for us at the Eperquerie, and can get a boat there to put us aboard, we might manage Alderney.”

“Sounds a bit if-fy, but tempting thereby.  Margaret, my dear, our work is cut out for us.”

“And Mr. Graeme’s cut out from him, I’m afraid.”

“Oh, not at all, I assure you.  It’s going ahead like steam,” and they began to descend into Greve de la Ville, the dogs as usual ranging the cliff-sides after rabbits, disappearing altogether at times and then flashing suddenly into view half a mile away among the gorse and bracken.

Sark scrambling requires caution and constant asistance from the practised to the unpractised hand, and Graeme omitted none of the necessary precautions.  Whereby Margaret’s throbbing hand was much in his,—­so, indeed, was Miss Penny’s, but that was quite another matter,—­and every convulsive grip of the little hand, though it was caused by nothing more than the uncertainties of the way, set his heart dancing and riveted the golden chains still more firmly round it.

There are difficult bits in those caves in the Greve de la Ville,—­steep ascents, and black drops in sheer faith into unknown depths, and tight squeezes past sloping shelves which seem on the point of closing and cracking one like a nut; and when they crawled out at last into a boulder-strewn plateau, open to the sea on one side only, they sighed gratefully at the ample height and breadth of things, and sank down on the shingle to breathe the free air and sunshine.

He amused them by telling them how, the last time he was there, he found an elderly gentleman sitting with his head in his hands, on that exact spot.  And how, at sight of the new-comer, he had come running to him and fallen sobbing on his neck.  He had been there for over an hour seeking the way out, and not being able to find it, had got into a panic.

“I wonder if you could find the place we came in, now?” said Graeme.  “Scamp, lie down, sir, and don’t give me away!”

“Why, certainly, it’s just there,” said Miss Penny, jumping up energetically and marching across, while the dogs grinned open-mouthed at her lack of perception.  For it wasn’t there at all, and she searched without avail, and at last sat down again saying, “Well, I sympathise with your old gentleman, Mr. Graeme.  If I was all alone here, and unable to find that hole, I should go into hysterics, though it’s not a thing I’m given to.  I suppose we did get in somehow.”

“Obviously!  And that’s where the advantage of a guide comes in, you see.”

“I, for one, appreciate him highly, I can assure you.  Where is that wretched hole?”

“Here it is, you see.  It’s a tricky place.  I shall never forget the look of relief on that old fellow’s face at sight of me.  I believe he thinks to this day that I saved his life.  He stuck to me like a leech all the way through the further caves and till we got back to the entrance.”
