“Don’t suppose they did, sir. Sound runs in a still, dark night like this. Well, anyways it seems to me as it’s quite time we had a good look round to see if there’s a hole anywhere in the bottom of the pot, so if you’re ready, so am I. Only say the word.”

“Forward!” cried Roy; and, going first with the lantern, Ben led the way along the corridor to the head of a flight of stone steps, down which they went to the underground passage, which with groined roof ran right along all four sides of the castle. The dark place seemed full of whispering echoes, as they went on past door after door leading into cellar and dungeon, all now turned into stores; for the great mass of provender brought in by Farmer Raynes’s wagons had here been carefully packed away, the contents of each place being signified by a white, neatly painted number, duly recorded in a book where the account of what number so-and-so indicated was carefully written in Master Pawson’s best hand, since he had eagerly undertaken the duties of clerk.

At each corner of the castle basement, the passage expanded into a circular crypt with a huge stone pillar, many feet in diameter, in the middle, from which radiated massive arches to rest on eight smaller pillars. This radial series of arches supported one of the towers, and, after passing the one to the north-east, Ben led on with his lantern along the passage running to the tower at the north-west corner, the dim light casting strange shadows behind, which seemed to be moving in pursuit of the two silent figures, urged on by the whispering echoes of their steps.

The pavement was smooth and perfectly dry, as were the massive stone walls; and as they went on, Roy fell into a musing fit, and thought of what a strongly built place Royland castle was, and how in times of emergency, if a garrison were hard pressed and had to yield rampart and tower to a powerful enemy, they would still have these passages and crypts as a place of refuge from which, if a bold defence were made, it would be impossible to dislodge them.

Apparently mind does influence mind under certain circumstances, for, just as Roy had arrived at this point, Ben stopped short and turned.

“Look here, Master Roy,” he said, “you ought, now we’re getting in pretty good order, to do two things.”

“Yes; what are they?”

“Have that there stone gallows on the ramparts put a bit in order. It wants a few stones and some mortar.”

“Why should I have that put in order?” said Roy, shortly.

“Case you want to hang any traitors, sir, for giving notice to the enemy of what we’re doing, or trying to open the gates to ’em.”
