Just then the cell door opened, and a shackled figure was thrust rudely in. It was Poblath, the mango. His captor was Trisp, the bar-mango.

It was now Trisp’s turn to gloat. Said he: “Long have I served as your assistant, O Poblath, and long have I coveted your position. Now it is mine for the asking. I suspected you of treason when you deprived Cabot of his antennae. I noted that you preserved his apparatus in a cupboard in your office. But when you refused to permit the jailers to fire on the insurgent blockade in the street below, then I knew for sure of your treason to King Yuri. Now I go to clear the blockade. Thence to the king to be made mango of Kuana!”

He left. From the window, the three prisoners watched the insurgents below. In a few moments the jail opened fire on them, and they withdrew in disorder. Once more the street was clear for the passage of alien troops.

“But they are still cheering for King Kew,” wrote Hah.

By this time Poblath had begun to recover from the shock of his sudden incarceration. He called to the professor, and soon the latter had turned his back to the ex-mango and was rummaging beneath Poblath’s toga with his shackled hands. After considerable search he found what he was after, a small pouch containing three keys.

In a moment the prisoners were free of their handcuffs. Another moment and the cell door swung open. The prisoners emerged and glanced cautiously around.

The corridor outside was dark and silent. Most of the wardens were on the roof, firing at the insurgents who had returned to the attack with great force.

Cabot, Hah Babbuh and Poblath did not stop to release any of their companions, but hurried to the ground floor. On the way they met but two of the jail guards. Hah smashed in the skull of one with a handcuff; the other had the good judgment to join the party.

It scarcely seemed a moment before the big steel doors swung open at Poblath’s touch, to admit the besiegers. A brief exchange of greetings, and they swarmed up the stairs to clear the roof, while Myles and his two friends followed, to release the other prisoners.

Every prisoner, regardless of what he was in for, was given a chance at freedom if he would join Cabot’s forces, and none refused. They were all freed by the time the party from the roof returned with sufficient captured arms to equip nearly all the rest. On the roof every warden lay dead.
