Directly after tea all the boys paid a visit to the shed; the door was securely locked, as also was the one leading into Locker's Lane, and it seemed impossible for the Philistines to carry out their evil designs upon the fireworks.

"I believe it's all bunkum," said Acton, as they strolled back towards the house. "However, we'll come down as we said, and just see if anything happens."

Three boys, at all events, did very little work that evening, for it was impossible to concentrate one's mind on Caesar or on French verbs with such an adventure looming in the near future. How would the Philistines get at the fireworks? Would they change their minds, and instead of drowning them apply a slow match and blow up the shed? or would it, after all, turn out to be only a false alarm, raised by the boy Crump for the sake of the promised shilling?

These and other thoughts filled the minds of the trio as they sat frowning at the books in front of them. The clock seemed to go slower and slower, until they really began to wonder whether it had stopped. At length the long hand reached the half-past. Mr. Blake yawned, put down his paper, and said, "Put away your work, and pass on to supper."

Acton and Diggory, both tingling with excitement, lingered behind until the rest had left the room; then, when the coast was clear, they slipped out into the garden, and hurried down the sloping path. It was considerably lighter than it had been before tea; the clouds had cleared away, and there were plenty of stars.

"Locked," muttered Acton, examining the shed. "Locked," he repeated, trying the door leading into Locker's Lane. "I don't believe there's anything in it. They might get over the wall if one gave the other a leg up, but then how's the last man to get back again?"

"Well, if there's nothing in it," answered Diggory, "how should Joe
Crump have got to know we had any fireworks in the place? There must—
Hush! what's that?"

There was a sound of footsteps coming down the path from the house. "Cave!" cried Acton. "It's Blake; let's hide!"

Several shrubs growing in the garden and overhanging the boarded partition threw one corner of the playground into deep shadow. The boys rushed into the angle, and, crouching down in the inky darkness, were at once hidden from the view of any one who might advance even to within a few feet of their hiding-place.

They had hardly time to conceal themselves, when a man, the outline of whose figure they could just make out in the gloom, came through the garden door, and, advancing a few yards, stood still, turning his head from side to side as though looking to make sure that the quadrangle was empty.
