Paying no attention to Edgar, who was so entirely altered by his disguise as to defy recognition, the two men seized Sidi, and began to drag him into the house. Edgar sprang forward and struck one of them so heavy a blow in the face that he released his hold of Sidi and staggered back against the wall. Then with a shout of fury he drew his knife and rushed at Edgar. The latter also snatched his knife from his girdle, shifted it into his left hand, and threw himself into the usual boxing attitude with his left foot forward. The Maltese paused in his rush. This line of defence was altogether new to him. He had been engaged in many a fierce fray, but his opponents had always, like himself, fought with their knives in their right hands.
