Locke in the warden’s office, unsuccessful in making the prisoner talk, had evolved another scheme.

“Put me in the cell next to him,” decided Locke.  “I have a plan.”

It was while the false guard was reading the address on the note that Locke and the warden entered the cell row.  The guard hastily stuffed the message in his pocket as Locke and the warden passed up toward the empty next cell.

Locke went through all the actions of one who was being thrown into a cell, and the emissary in his own cell listened without suspecting anything.  Locke had arranged with the warden to leave the cell unlocked, but no sooner had the warden left than the guard, who had been observing, moved over and shot the bolts.

Here, then, was a predicament.  Locke could not give the alarm without putting the emissary in the next cell on guard.  Rapidly Locke revolved in his head scheme after scheme.  He was an expert on bolts and knew that at any moment he could release himself.  Should he do so now?  Instead he concluded to wait until the guard returned, for by the man’s actions Locke was sure that something queer was going on, although, naturally, he did not know what it was.  Accordingly Locke lay down on the bunk in the cell and decided to wait.

Some time later, at a deserted house not far from the rock-hewn den of the Automaton, the false prison guard might have been seen delivering the message which the prisoner had written to two other emissaries of the Automaton.

After a hasty conference they decided on their course of action.  Not only did he receive the money the prisoner had promised him, but the emissaries gave him minute instructions regarding the rescue which they planned.  A cap and a pair of goggles for the prisoner were given to the guard and he was sent on his way.

Scarcely had he gone when the Automaton himself entered the deserted house, and under his direction one of the emissaries wrote a note which he addressed to Eva.  For, with Locke out of the way, it was a splendid time to take advantage of the poor girl.

The note read simply:  “Our prisoner has confessed.  Meet me at the Cliff House at eight o’clock,” and bore the signature of Locke.

Thus, with their plans carefully laid, the Automaton and his emissaries plotted, and soon a messenger was on his way to Eva with the faked message.

Meanwhile, as the day wore on, the treacherous guard returned on duty at the prison, and at the first opportunity made his way to the cell in which the emissary was locked.  In a hoarse whisper he told the fellow of the success of his mission and of the plan, slipping to him the cap and goggles through the bars.

Locke had been waiting for hours impatiently on his bunk, but now was all attention, though he was careful not to betray it.  As the guard left and the emissary was trying on the cap and goggles, Locke came to his cell door.  Now was the time to act.
