"The sloop is dead ahead!" hailed Milo, though none on deck could detect anything of her in the blackness. Dolores listened intently; then twirled the wheel, and cried: "I hear her! Ready the grapnels?"

"Aye, ready!"

"Then watch—and heave!" she commanded; and with the suddenness of light the schooner swept around in a swift arc, the black shape of the flying sloop stood out against the angry sea crests, and the two vessels came together with a crash of timbers and a rattling of gear.

A distant rumbling of thunder succeeded a faint flash, and wind and rain came down with increased fury as if to balance the defection of the electric element. The darkness of Erebus fell upon the surging vessels, and men groped at the rails in a blind effort to make out a footing for boarding the sloop.

"Follow me; I want Yellow Rufe alive!" cried Dolores, leaving the wheel and springing to the bulwarks. Instinctively Peters stepped to the wheel, and as he passed his employer he leaned to whisper in his ear:

"Let them once leave these decks, sir, and we'll up hellum and away!"

Venner's eyes glittered at the prospect; but he could not see the faces of his friends; he could only hear Pearse's low tones beside him, and the mumbled words indicated no great agreement in the scheme. Uncertain, his mind confused between desire to escape and desire to see more of Dolores and her hidden cave of wonders, Rupert Venner hesitated in his decision; and in the next moment it was out of his power to decide. For Rufe, in desperation now, met the boarders at the rail, backed by his half-dozen crazed adherents, and murderous steel glittered dully against the inky sky.

"Beat down his cringing curs, but leave me Rufe!" cried Dolores, opposing her own dagger to the sweep of the pirate's cutlas. And as the schooner's crew roared at Hanglip's heels, storming over to the pitching sloop's decks to pursue mercilessly the panic-stricken runaways, the girl pitted agility and splendid knife-craft against the terror-driven strength and wolfish fury of the trapped traitor.

"Hah! Thy black heart fails thee!" taunted Dolores, leaping down from the rail to the schooner's streaming deck and thus avoiding a whistling stroke of Rufe's cutlas. The pirate fell forward with the impetus of his blow, and stumbled in a heap at the girl's nimble feet. "Up, man!" she cried, leaping back to permit him to rise. "What, art afraid of a woman? Here, then, I prick thee! Now wilt fight?" She darted her dagger swiftly downward, and the partially healed cross on Rufe's cheek blazed red again.

"Woman or devil, I'll see thy heart for that!" swore the pirate, and rose with a bound and hurled himself at the girl. She stepped aside agilely and laughed mockingly at him, while as he again stumbled with the swing of his avoided blow she darted close, and her knife ripped his sword-arm from wrist to elbow.
