when a heavily goggled man climbed out and
signaled to him. In the back of the car was another man, also goggled,
while the chauffeur, alone, had his face also well hidden by a cap over
his eyes and his collar pulled up.

Understanding perfectly, the guard hurried into the jail, making sure
that the coast was clear, and down the cell row to the cell where Locke
was waiting impatiently, now dressed and hunched up in a perfect
imitation of the emissary. The turnkey opened the door and whispered to
Locke, who nodded gruffly, and together they sneaked quietly out.

With scarcely another word, outside, Locke leaped into the waiting car
and the four were off, leaving the false turnkey chuckling over his
cleverness and ready to make a get-away.

Locke glanced furtively from the driver to the other two passengers in
the car as it sped along in the direction of the cliffs. So far
everything had gone fine. When would they begin to suspect the
substitution he had played on them? He revolved rapidly in his mind just
what he would do under various circumstances.

"Well, old pal," exclaimed one, clapping him on the shoulders, "how does
it seem to be out?"

Locke replied with gruff heartiness, and the others now began to remove
their goggles. Locke, however, did not do the same. They exchanged a

Already Eva had arrived at the Cliff House, had left her car, and was
approaching on foot, just as Locke with the now thoroughly aroused
emissaries swung into sight.

With a shout to the driver, the two in the back of the car leaped at
Locke at once, and, as the car stopped, the chauffeur joined them.

Even prepared as he was, Locke was no match for three of them, and,
fighting furiously, all four combatants rolled over and over as they
came closer to the door of an old acid-mill that adjoined the Cliff
House.

"We must keep him from saving the girl," panted the leader of the
emissaries to the others.

Inside the old building stood some huge tanks of acid, and as they
rolled nearer and nearer to them it became evident that Locke was in
their power.

Suddenly one emissary reached out and secured a coil of rope, which he
unwound quickly. The others, too, saw their chance. It was fiendish.
Round and round they wound the rope until they had Locke well-nigh
helpless. Then one of them cast the end of the coil over a beam, all
seized the end as it fell on the other side, and Locke found himself
dangling head downward from the
