Like his sister, he had thrown back his cloak, disclosing a brawny, powerful figure, leather clad, with a wide belt of dangling ornaments, some of which probably were weapons.

How long we gazed at this silent colored image of the restaurant table I do not know. I was aware of Halsey's quiet voice: "Look him over, Miss Venza. It depends on you."

Another interval passed. It seemed, as we watched, that Molo's interest in his party was very slight. I got the impression, too, that though at first he had seemed to be intoxicated, actually he was not. Nor was his sister. Anxiety seemed upon her; the smile she had for jests seemed forced; and at intervals she would cast a swift, furtive glance across the gay restaurant scene.

More drinks arrived. The Earthpeople at the table here seemed upon the verge of stupor; and suddenly it appeared that Molo had completely lost interest in them. With a gesture to his sister, he abruptly rose from his seat. She joined him. They left the table, and a red-clad floor manager of the restaurant came at their call. Then in a moment they were moving across the room.

Halsey called sharply into his audiphone: "Francis! Hold us to them if you can."

They were standing now by the opened door of one of the Red Spark's private insulated rooms. We caught a glimpse of its interior, a gaily set table with a bank of colored lights over it.

The figure of a man was in there. He was on his feet, as though he had just arrived to meet the Martians here, and a hooded long cloak enveloped him. It may have been a magnetic "invisible" cloak, with the current now off.

We caught only the fleetest of impressions before the insulated door closed and barred our vision. The glimpse was an accident. Molo, taken by surprise at this appearance of his visitor, could hardly have guarded against it. The waiting figure was very tall, some ten feet, and very thin. The hood shrouded his face and head. In his hand he held a large circular box of black shiny leather, of the sort in which women carry wide-brimmed hats. As Molo joined him he put the box gently on the floor. He handled it as though it were extraordinarily heavy; and as he took a step or two, he seemed weighted down. Just as the room door was hastily closing, Meka sliding it from the inside, we caught a fleeting glimpse of horror.

The lid of the hat box had lifted up. Inside was a great round thing of gray-white, a living thing; a distended ball of membrane, with a network of veins and blood-vessels showing beneath the transparent skin.

For the instant we gazed, stricken. The ball was palpitating, breathing! I saw convolutions of inner tissue under the transparent skin of membrane; a little tentacle, like an arm with a flat-webbed hand, was holding up the lid of the box. The lid rose a trifle higher; the colored lights overhead gave us a brief but clear view of it.
