Nayland Smith's Browning spat death across the cave. Then followed the report of Barton's pistol; then those of mine and Kennedy's.

A small motor-boat was creeping cautiously out under a low, natural archway which evidently gave access to the sea! Since the tide was incoming, a few minutes more of delay had rendered the passage of the cavern impossible….

The boat disappeared.

"We are not beaten!" snapped Nayland Smith. "The Chanak-Kampo will be seized in the Channel!"

"There were formerly steps, in the side of the well from which this place takes its name," declared Nayland Smith dully. "This was the means of access to the secret chapel employed by the devil-worshipers."

"The top of the well (alleged to be the deepest in England)," said
Sir Lionel, "is among a tangle of weeds close by the ruined tower."

Smith, ascending three stone steps, swung the lantern out over the yawning pit below; then he stared long and fixedly upwards.

Both thunder and rain had ceased; but even in those gloomy depths we could hear the coming of the tempest which followed upon that memorable storm.

"The steps are here," reported Smith; "but without the aid of a rope from above, I doubt if they are climbable."
