It was pitch-dark in the dormitory, but Mike could follow the invaders' 　　movements as clearly as if it had been broad daylight. They had openedthe door and were listening. Jellicoe's breathing grew more asthmatic;he was flinging himself into his part with the whole-heartedness of thetrue artist. 　　The creak was followed by a sound of whispering, then another creak. 　　The enemy had advanced to the top step.... Another creak.... Thevanguard had reached the second step.... In another moment----CRASH! 　　And at that point the proceedings may be said to have formally opened. 　　A struggling mass bumped against Mike's shins as he rose from hischair; he emptied his jug on to this mass, and a yell of anguishshowed that the contents had got to the right address. 　　Then a hand grabbed his ankle and he went down, a million sparksdancing before his eyes as a fist, flying out at a venture, caught himon the nose. 　　Mike had not been well-disposed towards the invaders before, but nowhe ran amok, hitting out right and left at random. His right missed,but his left went home hard on some portion of somebody's anatomy. Akick freed his ankle and he staggered to his feet. At the same momenta sudden increase in the general volume of noise spoke eloquently ofgood work that was being put in by Psmith. 　　Even at that crisis, Mike could not help feeling that if a row of thiscalibre did not draw Mr. Outwood from his bed, he must be an unusualkind of house-master. 　　He plunged forward again with outstretched arms, and stumbled and fellover one of the on-the-floor section of the opposing force. Theyseized each other earnestly and rolled across the room till Mike,contriving to secure his adversary's head, bumped it on the floor withsuch abandon that, with a muffled yell, the other let go, and for thesecond time he rose. As he did so he was conscious of a curiousthudding sound that made itself heard through the other assortednoises of the battle.
