And in an instant there was pandemonium.

A door flew open, and, clashing heavily against the wall, sent an echo reeling along the corridor; then came a clatter of rustling feet, a voice cried out excitedly: "Come on! come on! He's had to kill the old fool to get it!" and Cleek had just time to tear loose from the shape with which he was battling, and dodge out of the way when the man Merode lurched into the room, with half a dozen Apaches tumbling in at his heels.

"Serpice!" he cried, rushing forward, as he saw the gasping red shape upon the floor; "Serpice! Mon Dieu! what is it?"

"The Cracksman!" he gulped. "Cleek!—the Cracksman who went against us! Catch him! stop him!"

"The Cracksman!" howled out Merode, twisting round in the darkness and reaching blindly for the haft of his dirk. "Nom de Dieu! Where?"

And almost before the last word was uttered a fist like a sledge-hammer shot out, caught him full in the face, and he went down with a whole smithy of sparks flashing and hissing before his eyes.

"There!" answered Cleek, as he bowled him over. "Gentlemen of the sewers, my compliments. You'll make no short cut to 'The Twisted Arm' to-night!"

Then, like something shot from a catapult, he sprang to the door, whisked through it, banged it behind him, turned the key, and went racing down the corridor like a hare.

"It must be sheer luck now!" he panted, as he reached the angle and, kicking aside the rug, pulled up the trap. "They'll have that door down in a brace of shakes, and be after me like a pack of ravening wolves. The race is to the swift this time, gentlemen, and you'll have to take a long way round if you mean to head me off."
