"That'd be too bad, wouldn't it!"

"We could starve 'em out, for that matter," said Grim. "But they've probably got water down there, and perhaps food. Every hour of delay adds to the risk of rioting. We've got to get this hole sealed up permanently, and deny that it was ever opened."

"We could do that at once! But I won't be a party to sealing 'em up alive."

"Besides, sir, they've certainly got firearms, and they might just possible have one can of TNT down there."

"All right," said Goodenough. "I'll lead the way down."

"I've a plan," said Grim.

He took one of the fruit-baskets and began breaking it up.

"Who has a white shirt?" he asked.

I was the haberdasher. The others, Sikhs included, were all clothed in khaki from coat to skin. Grim's Bedouin array was dark-brown. I peeled the shirt off, and Grim rigged it on a frame of basket-work, with a clumsy pitch-forked arrangement of withes at the bottom. The idea was not obvious until he twisted the withes about his waist; then, when he bent down, the shirt stood up erect above him.

"If you don't mind, sir, we'll have two or three Sikhs go first. Have them take their boots off and crawl quietly as flat down as they can keep. I'll follow 'em with this contraption. They'll be able to see the white shirt dimly against the tunnel, and if they do any shooting they'll aim at that. Then if the rest of you keep low behind me we've a good chance to rush them before they can do any damage."
