man, without a bed, without blankets, without even
a tooth-brush."

"He hasn't been wholly off my mind," I answered truthfully. "But there
isn't anything we can do to-night, with that beastly detective to notice
it."

"Then you must go very early to-morrow morning, before the detective gets
up."

I couldn't help smiling at the notion of getting up before a detective.

"I am only too willing," I said.

"It must be by four o'clock," Miss Thorn went on energetically, "and we
must have a guide we can trust. Arrange it with one of Uncle Fenelon's
friends."

"We?" I repeated.

"You certainly don't imagine that I am going to be left behind?" said

I made haste to invite for the expedition one of the Four, who was quite

one of the tents drawn back and two figures emerge. They came and stood
on the bank above, under the tree which sheltered me. And I experienced
a curious phenomenon. I heard, and understood, and remembered the first
part of the conversation which passed between them, and did not know it.

"I am sorry to disturb you," said one.

"Not at all," said the other, whose tone, I thought afterwards, betokened
surprise, and no great cheerfulness.

"But I have had no other opportunity to speak with you."

"No," said the other, rather uneasily.

Suddenly my senses were alert, and I knew that Mr. Trevor had pulled the
detective out of bed. The senator had no doubt anticipated an easier
time, and he now began feeling for an opening. More than once he cleared
his throat to commence, while Mr. Drew pulled his scant clothing closer
