If he is some outsider, we'll round him up. I rather think the
former--it's too early to make a guess. But I think we'd better appoint
a guard over the body--to keep any curious persons from coming near and
tramping out footprints, and so on. There's apt to be a crowd of the
curious here to-morrow."

All of us nodded. Lemuel Marten whispered an oath.

Nopp turned to him. "Would you mind taking that post to-night, Marten?"
he asked. Because he already knew the man's answer, he turned to us.
"Lem's the best man for the post," he explained. "You chaps know we'll
all have to give an account of our actions to-night. It's customary at
such times. And you know that Lem was busy singing his pirate song when
the thing occurred."

"That's an unnecessary point, Joe," Marten answered. "None of us will be
in the least suspected. This poor chap--that none of us knew. However,
I'll gladly enough act as guard."

"You've still got your gun?"

"I made Pescini carry it. He's a shot."

Pescini handed him back the weapon, and Marten walked on across the lawn
to his post. The rest of us waited an instant in the road, talking
quietly to one another, and two or three of the men were getting out
their cigarettes. It was our first breathing-spell. Then we started
slowly back toward the house.

But we halted at the sound of Marten's voice. "Wait a minute, will you?"
he called.

It is hard to explain why we all stopped in our tracks. Van Hope, whom I
had never suspected of nerves, let his cigarette fall to the ground, a
red streak. The voice out of the gloom was wholly quiet, subdued,
perfectly calm, seemingly nothing to waken alarm or even especial
interest. Perhaps what held us and startled us was the realization of an
effort of will behind those commonplace, unruffled tones.

"What is it, Lem?" Nopp asked.

There was an instant's interval of unfathomable silence. "I wish you'd
come here," Marten replied. "I'm a little balled up--as to where I am.
These trees and shrubs are so near alike. I can't exactly find--the
place."

Nopp did get there, but he didn't go alone. All of us turned,
half-running. And for a vague, bewildered, half-remembered moment we
searched frantically up and down the craggy shore of the lagoon.

Then in the moonlight I saw Nopp and Nealman come together, and Nopp
seized the other's arms.

"My God, Grover!" he said hoarsely. "The body has disappeared!"
