"By Jingo!" cried Sievers. "I see your game. Let me look, Maclean! This is my trade."
He bent forward, wrenched at a shoot-bolt, and with a cry of satisfaction threw back a plate. The Saigon's company crowded round the man-hole thus revealed, muttering with excitement.
"One moment, Sievers!" cried Maclean, for the engineer had one leg already in the tunnel. Then he turned to the men. "My lads," he said, "it's a case of our lives or the Russians', for I firmly believe the accursed pirates mean to kill us. We must take this ship by hook or by crook, and I think I see the way to do it!" He concluded with some precise instructions, and a few savage sentences, in which he promised an unmentionable fate to the unfortunate who made a sound or failed to follow to the letter his instructions.
A second later, in a silence that could be felt, he blew out the light, and followed Sievers into the tunnel. A few cave-black yards, crawled painfully on hands and knees, slipping and slithering along the propeller shaft, brought the leaders to the edge of a wider space. Sievers struck a match, and a well-like, vertical opening was revealed. High overhead towered and threatened an enormous steel crank. Before their feet lay a deep pool of slime. The heat was horrible.
"It should be hereabouts," whispered Sievers, and his fingers searched the wall. For a moment nothing could be heard but the deep breathing of the Saigon's company. Then came a slight but terrifying clang.
"I've got it!" whispered Sievers. "Are you ready?"
"Right!"
Maclean's eyes were dazzled of a sudden with a hot flare of light, and the deafening thud of the condensers smote in his ears. He never quite coherently remembered that which immediately ensued, for something struck him on the head.
When he came to his full senses again he was lying on a grating beside the body of the Russian cleaner he had strangled. The Saigon's men were all around him. He arose, gasping for breath. Sievers thrust a bar into his hand and pointed to a line of ladders. Maclean nodded, crossed the grating, and began to climb. Sievers, armed with a hammer, followed at his heels.
There were three men in the engine-room, an engineer and two cleaners. They took the climbers for stokers, and went on with their occupations. Maclean sidled to the door across the grating and closed it in the twinkling of an eye. The engineer, who was reading a newspaper, heard the noise and looked up. Sievers struck him with the hammer and flew at one of the cleaners. Maclean rushed at the other with his spade. It was all over in a moment, and without any noise that the thudding of the donkey-engine did not drown. Maclean changed coats and caps with the insensible Russian engineer, while Sievers called the Saigon's men from below. He then strapped on the man's dirk, and put his revolver in his pocket.
