Thorn drew a deep breath. He was inside the Arvanian Embassy. The place was a three-storied stone trap in which, if the slightest slip revealed him to its tenants, he would surely meet his death. But, anyway, he was inside! And the threatening Ziegler plans waited somewhere near at hand for him to find and take!

Even had Thorn not known in advance that trouble was brewing, he could have surmised that something sinister was being hatched in the Arvanian Embassy. For, in this big sunny kitchen five men lounged about in addition to the white-coated chef and his beardless stripling of an assistant. And each of the five had a holster strapped openly over his coat with the butt of an automatic protruding in plain sight.

Thorn looked about. Across from the great range, beside which he was standing and holding his breath for fear some one of the seven men should become aware of his presence, was the door leading to the front part of the house. He started toward that door, walking on tiptoe. A shudder crept up his spine as he tiptoed across the floor directly in front of the armed guards who would have shot him down without compunction could they have seen him. He was not yet used to his invisibility; knowing himself to be substantial, feeling his feet descend solidly on the floor, he still could hardly credit the fact that human eyes could not observe him.


He got to the door. He put out his hand to open it, then realized just in time that he could not do that. A door stealthily opening and closing again, with no apparent hand to manipulate it? Such a spectacle would start a riot!

In a frenzy of impatience, he stood beside the door, waiting till someone else should swing it open. And in a moment it chanced that the stripling assistant chef came toward him with a tray. The boy pushed the swinging door with his foot, and walked into the butler's pantry. After him, treading almost on the lad's heels, came Thorn.

The boy sat the tray down, and turned to reach into an upper shelf. The space in the pantry was constricted, and he turned abruptly. The result was that he suddenly drew back as though a hot iron had seared him, and went white as chalk. Then he dashed back into the kitchen.

"A hand!" Thorn heard him gibbering in Arvanian. "A hand! I touched it with mine! Something horrible is in there!"

With his heart pounding in his throat, Thorn leaned close to the swing-door to hear what happened next. Would there be a rush for the butler's pantry? An investigation? He eyed the farther door—the dining room door. But he dared not flee through that save as a last resort. In the dining room sounded voices; and again the sight of a door opening and closing of itself would lead to uproar.

"A hand?" he heard one of the guards say in the kitchen. "An unseen hand? Thou art empty in the head, young Gova."
