"This is the little devil," he said, indicating his delicate burden.
"Fulminate of mercury. This is the stuff that"ll remove your hand with neatness and despatch. It"s the quickest tempered little article in the business. Just give it one hard look and it"s off."
"Here," said Trendon, "I resign. From now on I"m a spectator."
Barnett swung the fulminate in his handkerchief and gave it to a sailor to hold. The man dandled it like a new-born infant. Back to his rock went Barnett. Producing some cord, he let down an end.
"Tie the handkerchief on, and get out of the way," he directed.
With painful slowness the man carried out the first part of the order; the latter half he obeyed with sprightly alacrity. Very slowly, very delicately, the expert drew in his dangerous burden. Once a current of air puffed it against the face of the rock, and the operator"s head was hastily withdrawn. Nothing happened. Another minute and he had the tiny sh.e.l.l in hand. A fuse was fixed in it and it was shoved under the mud-cap.
Barnett stood up.
"Will you kindly order the boat ready, Captain Parkinson?" he called.
The order was given.
"As soon as I light the fuse I will come down and we"ll pull out fifty yards. Leave the rest of the Joveite where it is. All ready? Here goes."
He touched a match to the fuse. It caught. For a moment he watched it.
"Going all right," he reported, as he struck the water. "Plenty of time."
Some seventy yards out they rested on their oars. They waited. And waited.
And waited.
"It"s out," grunted Trendon.
From the face of the cliff puffed a cloud of dust. A thudding report boomed over the water. Just a wisp of whitish-grey smoke arose, and beneath it the great rock, with a gapping seam across its top, rolled majestically outward, sending a shower of spray on all sides, and opening to their eager view a black chasm into the heart of the headland. The experiment had worked out with the accuracy of a geometric problem.
"That"s all, sir," Barnett reported officially.
"Magic! Modern magic!" said the captain. He stared at the open door. For the moment the object of the undertaking was forgotten in the wonder of its exact accomplishment.
"Darrow"ll think an earthquake"s come after him," remarked Trendon.
"Give way," ordered the captain.
The boat grated on the sand. Captain Parkinson would have entered, but Barnett restrained him.
"It"s best to wait a minute or two," he advised. "Occasionally slides follow an explosion tardily, and the gases don"t always dissipate quickly."
Where they stood they could see but a short way into the cave. Trendon squatted and funnelled his hands to one eye.
[Ill.u.s.tration: "Sorry not to have met you at the door," he said courteously.]
"There"s fire inside," he said.
In a moment they all saw it, a single, pin-point glow, far back in the blackness, a Cyclopean eye, that swayed as it approached. Alternately it waned and brightened. Suddenly it illuminated the dim lineaments of a face. The face neared them. It joined itself to reality by a very solid pair of shoulders, and a man sauntered into the twilit mouth of the cavern, removed a cigarette from his lips, and gave them greeting.
"Sorry not to have met you at the door," he said, courteously. "It was you that knocked, was it not? Yes? It roused me from my siesta."
They stared at him in silence. He blinked in the light, with unaccustomed eyes.
"You will pardon me for not asking you in at once. Past circ.u.mstances have rendered me--well--perhaps suspicious is not too strong a word."
They noticed that he held a revolver in his hand.
Captain Parkinson came forward a step. The host half raised his weapon.
Then he dropped it abruptly.
"Navy men!" he said, in an altered voice. "I beg your pardon. I could not see at first. My name is Percy Darrow."
"I am Captain Parkinson of the United States cruiser _Wolverine_," said the commander. "This is Mr. Barnett, Mr. Darrow. Dr. Trendon, Mr. Darrow."
They shook hands all around.
"Like some d.a.m.ned silly afternoon tea," Trendon said later, in retailing it to the mess. A pause followed.
"Won"t you step in, gentlemen?" said Darrow, "May I offer you the makings of a cigarette?"
"Wouldn"t you be robbing yourself?" inquired the captain, with a twinkle.
"Oh, you found the diary, then," said Darrow easily. "Rather silly of me to complain so. But really, in conditions like these, tobacco becomes a serious problem."
"So one might imagine," said Trendon drily. He looked closely at Darrow.
The man"s eyes were light and dancing. From the nostrils two livid lines ran diagonally. Such lines one might make with a hard blue pencil pressed strongly into the flesh. The surgeon moved a little nearer.
"Can you give me any news of my friend Thrackles?" asked Darrow lightly.
"Or the esteemed Pulz? Or the scholarly and urbane Robinson of Ethiopian extraction?"
"Dead," said the captain.
"Ah, a pity," said the other. He put his hand to his forehead. "I had thought it probable." His face twitched. "Dead? Very good. In fact ...
really ... er ... amusing."
He began to laugh, quite to himself. It was not a pleasant laugh to hear.
Trendon caught and shook him by the shoulder.
"Drop it," he said.
Darrow seemed not to hear him. "Dead, all dead!" he repeated. "And I"ve outlasted "em! G.o.d d.a.m.n "em, I"ve outlasted "em!" And his mirth broke forth in a strangely shocking spasm.
Trendon lifted a hand and struck him so powerfully between the shoulder blades that he all but plunged forward on his face.
"Quit it!" he ordered again. "Get hold of yourself!"
Darrow turned and gripped him. The surgeon winced with the pain of his grasp. "I can"t," gasped the maroon, between paroxysms. "I"ve been living in h.e.l.l. A black, shaking, shivering h.e.l.l, for G.o.d knows how long.... What do you know? Have you ever been buried alive?" And again the agony of laughter shook him.
"This, then," muttered the doctor, and the hypodermic needle shot home.
