"That's a job for you," replied Brent, with a suggestive glance. "And, if I might suggest it, why not make a thorough examination of the Moot Hall? My cousin showed me over it when I was here last, and I remember some queer places in it."

"There are queer places in it," admitted Hawthwaite. "But it's hardly likely the murderer would hang about after doing what he did. Of course I'll have the whole place searched thoroughly—every inch of it!—for any possible clues and traces. We shall neglect nothing in a case of this sort, I can assure you, Mr. Brent. I—But come into my office."

He led the way into a drab-walled, official-looking apartment, curiously suggestive of the lesser and meaner forms of crime, and pointed to a chair.

"Sit down," he said. "As I was about to say——"

"Oughtn't one to be doing something?" interrupted Brent, refusing the chair. "That's what I feel anyway. Only what can one do?"

"Ah, that's just it!" exclaimed Hawthwaite. "You may feel as energetic as you will, but what can you do? The doctors are doing the absolutely necessary things at present; as for me, all I can do is to search for clues and traces, as I suggested, and make all possible inquiries. But there you are, we've nothing to go on—nothing, I mean, that would identify."

Brent gave the superintendent a keen glance.

"Between ourselves," he said, "have you any reason for suspecting anyone?"

Hawthwaite started. His surprise was genuine enough.
