"But the door's unlocked, sir," announced the lieutenant, with something like dismay.

"Unlocked!" echoed the Doctor.

The Captain blushed.

"I could have sworn, Doctor, I turned the key in the lock before leaving last Thursday. I think my head must be going. I've been sleeping badly of late—it's this worry about Fugler. However, I don't suppose anybody—"

A yell interrupted him. It came from Uncle Issy, who had entered the store-hut, and now emerged from it as if projected from a gun.

"THE FRENCH! THE FRENCH!"

For two terrible seconds the Die-hards eyed one another. Then someone in the rear rank whispered, "An ambush!" The two ranks began to waver—to melt. Uncle Issy, with head down and shoulders arched, was already stumbling down the slope towards the town. In another ten seconds the whole Company would be at his heels.

The Doctor saved their reputation. He was as pale as the rest; but a hasty remembrance of the cubic capacity of the store-hut told him that the number of Frenchmen in ambush there could hardly be more than half a dozen.

"Halt!" he shouted; and Captain Pond shouted "Halt!" too, adding, "There'll be heaps of time to run when we find out what's the matter."

The Die-hards hung, still wavering, upon the edge of the platform.
