There's somebody here ahead of us."

All looked where Haskell pointed, and they were able to make out the
figure of a man standing in one of the numerous paths which wound
through the garden. He appeared not to have noticed the advancing party.

"He isn't ten feet from the grave," whispered Haskell. "It's under that
tree right beside him."

At this moment the moon broke through the cloud. Its light fell round
the figure in the path.

It was Dr. Jarvis.

Nick's first thought was that this was another sleep-walking wonder, but
in a second this idea was dispelled.

The doctor saw the intruders. He uttered an exclamation, and seemed
about to retreat in the direction of the hospital. Then summoning up his
courage, he paused, and confronted them as they came forward.

"Who are you?" he asked, in a trembling voice.

"I'll soon show you who I am?" cried Deever, angrily, "and I'll show
these gentlemen what you are, in a few minutes."

"Lawrence Deever!" cried the doctor.

"Yes; I'm Lawrence Deever," was the reply, "and I've come to find my

"You are a fool and a knave," the doctor exclaimed. "Your brother is not

"We'll see about that."

"I order you to leave this garden."

"I wouldn't do that if I were you," said Nick, stepping forward. "I have

In a few words he showed Dr. Jarvis the futility of resistance. Nick
explained in a few words the evidence of Haskell, and made no attempt to
conceal its true bearing upon the case.

He spoke with his customary calm and steady tone, and his words seemed
to reassure the doctor.

"The fellow is a liar and the tool of a liar," said the doctor, glaring
at Deever. "I shall challenge you to find that body in this garden."

"It's here, unless you've taken it away," said Deever, roughly. "Now,
Haskell, show us the spot, and we'll go to work."

Thus urged, Haskell, who had hung back, as if afraid, stepped forward
with no sign of hesitation, and pointed to the ground under one of the
trees.

"He was at work just under this long limb," said Haskell.

Nick bent down to examine the ground. It was a flower-bed which looked
as if it had recently been sown.

The spot was excellently chosen for concealment. It was impossible to
tell whether the earth there had recently been disturbed.

Deever seized a spade and began to dig. He was a man of enormous
strength, and he worked furiously.
