clamor and confusion, Doctor Benoit enters the
court room, and almost unobserved seats himself beside the New York
medical experts.

A smile of gratification comes to O'Meara's face at sight of this late
arrival, and when the court is restored to quiet, he says:

"Let Doctor Benoit be sworn."

The doctor testifies as follows:

Being called to examine the wounds upon the person of John Burrill, he
found that they could not have been made with the knife found with the
body. The identical knife being put into his hands, he explains how a
cut made by such a keen, heavy weapon, must appear, and describes the
knife that must have been used upon the body.

"It was a smaller weapon," he says, "thinner bladed and much lighter. It
must have been shorter by two or three inches."

Then he adds that the surgeon's knife has never been used upon a body;
the blood has been smeared on by an inartistic hand.

"It would be impossible," he says, "to withdraw this knife from a
bleeding wound with no other blood marks than those it bears."

Doctor Gaylor and Professor Harrington corroborate his every statement,
and when their testimony is done there is another sensation in the court
room.

As Doctor Benoit passes by O'Meara, in returning from the witness stand,
he tosses over a piece of paper, which the lawyer seizes, scans eagerly,
and stows carefully away.

He consults some papers for a moment, and then says:

"I wish to recall Francis Lamotte."

Frank comes again upon the stand; his eyes seem fixed on vacancy; his
face is white and rigid; his answers come in a dry monotone.

"Mr. Lamotte," begins O'Meara, briskly. "It is understood that you have
been a student in Doctor Heath's office."

"That is true."

"During the time you studied there, had you free access to the office at
all hours?"

"I had."

"I judge, then, that you must have possessed a pass key?"

"I did."

"Is that key still in your possession?"

"No."

"How did you dispose of that key?"

"I think it was lost; it has been out of my possession for some time."

"Where did you lose this key?"

"I do not remember; possibly at home, possibly at the office. It has
been out of my possession for some time."

"Since losing your key, how did you gain access to the office in the
doctor's absence?"

"I have visited the office very seldom of late, and not once since
losing the key, in the absence of Doctor Heath."

"Mr. Lamotte, was there any way to disti
