On this, the last occasion of his three visits to the library, he once again worked the lock of the side door and overhauled his handiwork. Lord Sepulchrave had been there on the previous night as usual, but apparently had suspected nothing. The tall book stand was as he had left it, obstructing a view of and throwing a deep shadow over the handle of the main door from beneath which the twisted cloth stretched like a tight rope across the two foot span to the end of the long book shelves. He could now detect no smell of oil, and although that meant that it was evaporating, he knew that it would still be more inflammable than the dry cloth.

Before he left he selected half a dozen volumes from the less conspicuous shelves, which he hid in the pine wood on his return journey, and which he collected on the following night from their rainproof nest of needles in the decayed bole of a dead larch. Three of the volumes had vellum bindings and were exquisitely chased with gold, and the others were of equally rare craftsmanship, and it was with annoyance, on returning to the Prunesquallors’ that night that he found it necessary to fashion for them their neat jackets of brown paper and to obliterate the Groan crest on the fly-leaves.

It was only when these nefarious doings were satisfactorily completed that Steerpike visited the aunts for the second time and re-primed them in their very simple rôles as arsonists. He had decided that rather than tell the Prunesquallors that he was going out for a stroll he would say instead that he was paying a visit to the aunts, and then with them to prove his alibi (for somehow or other they must be got to and from the library without the knowledge of their short-legged servant), their story and that of the Doctor’s would coincide.

He had made them repeat a dozen or so times: ‘We’ve been indoors all the time. We’ve been indoors all the time,’ until they were themselves as convinced of it as though they were reliving the Future!

THE GROTTO

It happened on the day of Steerpike’s second daylight visit to the Library. He was on his return journey and had reached the edge of the pine woods and was awaiting an opportunity to run unobserved across the open ground, when, away to his left, he saw a figure moving in the direction of Gormenghast Mountain.
