The other bit his lips. 'Very well,' he said sullenly. 'I have no choice.'

'Look out for treachery, sir,' said Ken in a low voice. 'That man means mischief, I believe.'

'He is an ugly looking beggar. But what can he do?'

The words were hardly out of his mouth before the black-browed officer flung up his arm, with a pistol gripped in his fist, and fired straight at Commander Strang's head.

Quick as he was, Ken was quicker. As the man's arm came up, so did Ken's, and seizing Strang by the wrist, he jerked him back.

Before the man could fire a second time, one of the bluejackets had raised his rifle and shot him through the body.

'Thank you, Carrington,' said the commander, glancing at the gray splash of lead on the deck, just where he had been standing the previous moment, 'You were right, and I was wrong.

'Speak to them in their own language,' he continued coolly. 'Tell them I'll blow them out of the water if they try any more tricks of that sort.'

Ken's announcement was followed by dead silence aboard the steamer. Then a second officer appeared at the rail. He had both hands up.

'We surrender,' he said.
