"No," put in Billy. "She's getting off too easily. That's only sticking a knife in hen. They ought to twist the knife around."

"Even with all that," declared Tom, "she won't begin to pay for all the misery and death she caused. But what are they going to do with the Kaiser?" he continued. "Have you heard about that?"

"Oh, they're talking about yanking him out of Holland and putting him on trial," answered Frank; "but it's a gamble if they really will. He's such a skulking cowardly figure just now that perhaps it wouldn't be well to try him. It might dignify him too much, make a martyr of him. They may let him and the Crown Prince stay where they are. There's no telling."

"Well," remarked Tom, as they rose to their feet and started toward the barracks, "whatever the terms, I only hope they'll hurry them up and let us get back to the States."

A week of comparative quiet followed, and the situation in Coblenz seemed to be well in hand. That is, as far as disturbances were concerned. The mysterious disease, however, still seemed to be uncurbed, despite all the efforts of the medical staff.

Military restrictions now were somewhat relaxed. Leaves of absence were more easily obtained, but it was some time before the Army Boys were able to arrange things so that all their leaves fell on the same night.

That time came at last, however, and they started out soon after nightfall with the determination once for all to solve the mystery of the alley. The night was extremely dark, and as the moon would not rise till late they had comparatively little difficulty in seizing an opportunity when the street was practically deserted to slip into the alley unobserved.

Their task was rendered easier by the fact that there was no longer ice to hinder their raising of the trap door. It creaked under the straining of their arms, but it yielded, and, using the utmost caution, they descended into the yawning chasm.

They had provided themselves with stout sticks that they felt sure would enable them to ward off any attack by rats, though they devoutly hoped that these would not be needed. Nor were they, for Billy's conjecture that the part infested by them was beyond the lighted corridor proved correct.

With the stealth of Indians they moved along the narrow passage, darting glances into every opening that seemed to branch off from the main corridor. For some time nothing greeted their eyes but impenetrable blackness, and they began to think that either the light had been extinguished or that they had inadvertently passed it by.
