I made the guess at hazard, little knowing how near the truth it was to prove. We were almost at the head of the first stairway by this time, and the uproar in the corridor might have awakened the seven sleepers. Impossible, I said, that such a warning should not bring in men from the sea, sentinels who would ask by whose hand the key had been turned; but the danger lay behind us in the shadows where we had not looked for it. Aye, the three in the engine-house, how came I to forget them? They were atop of us before the doctor was out of hearing, and a great hulking German, his face smeared with soot and a bar of iron in his hands, caught me by the shoulder and swung me round almost before I had done speaking. "Who, in thunder, are you?" asks he. It was a question which had to be answered. Now, I had picked up a wrinkle or two about "rough-and-tumbles" in the years I traded to Yokohama, and though my heart was in my mouth and it was plain to me that this was the crisis of the night, when a single unlucky stroke or misspoken word might undo all that chance had done for us, I nevertheless kept my wits about me, and letting the man turn me round as he willed I presently caught his arm between both of mine and almost broke the bone of it. Upon which he lifted up a cry you might have heard at the sword-fish reef, and writhing down I struck him with all my force and he fell insensible. "Seven and one makes eight," said I, and a man might forgive himself for boasting at such a time; for, mark you, but two were left to deal with, and while one was making for little Dolly Venn, Peter Bligh had the throat of the other in such a grip that his friends might well have said, "God help him!" "Hold him, Peter, hold him!" cried I, my blood fired and my tongue set loose; but there was no need to be anxious for Mister Bligh, I do assure you. "He'll need new teeth to-morrow, and plenty of 'em!" says he, shaking the man as a dog shakes a rat. "Aye, go on, captain, the fun's beginning here." I waited to hear no more, but ran at the man who closed with little Dolly Venn. "Dolly's is the need," said I; though in that I was mistaken, as you shall see presently. And I do declare it was a picture to watch that bit of a lad dancing round a hulking Dutchman, and hitting the wind out of him as though he had been a cushion. Grunt? The lubber grunted like a pig, and every time he stopped for want of breath in come Master Dolly again with a lightning one which shook him like a thunder-bolt. No "set-to" that I have seen in all my life ever pleased me half as much; and what with crying and laughing by turns, and singing out "Bravo, Dolly!" and dancing round the pair of them, the sweat ran off me like rain, and I, and not little Dolly Venn, might have been doing for the Dutchman in the shadows of that corridor. In the end, believe me, this foreign bully turned tail and ran like a whipped cur. It was all I could do to keep the lad from his heels.
