A policeman came hurrying into the room, pulling himself up as he saw what was there. His voice instinctively hushed.
"Dr. Wellesley's just gone down Meadow Gate, sir," he announced. "They've sent for him to come here at once."
"Unless!" murmured the superintendent. "Still–"
Then the five or six men present stood, silently waiting. Some stared about the room, as if wondering at its secret: some occasionally took covert glances at its central figure. One of the three high, narrow windows was open: Brent distinctly heard the murmur of children playing in the streets outside. And suddenly, from the tower of St. Hathelswide, at the other end of the market-place, curfew began to ring.
"He's coming, sir!" whispered the policeman who stood near the door. "On the stairs, sir."
Brent turned as Dr. Wellesley came hurrying into the room; a tall, clean-shaven, fresh-coloured man, who went straight to the desk, looked at what he found there, and turned quickly on the men grouped around.
"How long is it since he was found?" he asked abruptly.
"Ten or twelve minutes," answered Brent.
"Dead then?"
"Yes," said Brent. "I should say—of course, I don't speak professionally—but I should think he'd been dead at least half an hour."
The doctor glanced at the superintendent.
"We must have him taken down to the mortuary," he said. "Let some of you men stay here with me, and send another for my assistant and for Dr. Barber."
The superintendent gave some orders, and touching Brent's arm motioned him to follow outside the room.
"This is a bad business, Mr. Brent!" he said as they paused at the head of the stair. "That's murder, sir! But how on earth did the murderer get in there? Bunning tells me that he himself was standing outside the iron gates at the entrance to the Moot Hall from the time the Mayor entered until you came. He asserts that nobody entered the place by those gates."
"I suppose there are other means of entrance?" suggested Brent.
"Doubtful if anybody could get in by them at this hour of the evening," answered the superintendent. "But there are two ways by which anybody could get to the Mayor's Parlour. They're both what you might call complicated. I'll show you them. Come this way."
He led Brent across a corridor that branched off from the head of the stone staircase, and presently stopped at a big double door.
"This is the Council Chamber," he said, as they entered a spacious apartment. "You see that door in the far corner, over there? There's a staircase leads down from that to the rooms that Bunning and his wife occupy as caretakers—a back stairs, in fact. But nobody can come up it, and through the Council Chamber, and along the corridor to the Mayor's Parlour without first coming through Bunning's rooms, that's flat. As for the other—well, it's still more unlikely."
He led Brent out of the Council Chamber and farther along to another door, which he flung open as he motioned his companion to enter.
"This is the Borough Court," he said. "Magistrates' bench, solicitors' table, and all the rest of it. And there's the dock, where we put the prisoners. Now, Mr. Brent, there's a staircase—a corkscrew staircase, modern, of ironwork—in the corner of that dock which leads down to the cells. And that's the second way by which you could get to the Mayor's Parlour. But just fancy what that means! A man who wanted to reach the Mayor's Parlour by that means of approach would have to enter the police station from St. Laurence Lane, at the back of the Moot Hall, pass the charge office, pass my office, go along a passage in which he'd be pretty certain to meet somebody, come up that stairs into the dock there, cross the court and—so on. That's not likely! And yet, those are the only ways by which there's access to the Mayor's Parlour except by the big staircase from the iron gates."
"What is certain," observed Brent, "is that the murderer did get to the Mayor's Parlour. And what seems more important just now is the question—how did he get away from it, unobserved? If Bunning is certain that no one entered by the front between my cousin's arrival and my coming, he is equally certain that no one left. Is it possible that anyone left by the police station entrance?"
"We'll soon settle that point!" answered Hawthwaite. "Come down there."
He opened the door of the dock and led Brent down an iron staircase into an arched and vaulted hall at its foot, whence they proceeded along various gloomy passages towards a heavy, iron-studded door. Near this, a police constable stood writing at a tall desk; the superintendent approached and spoke to him. Presently he turned back to Brent.
"There's nobody that he doesn't know has been in or out of this place during the whole of the evening," he said. "He's been on duty there since six o'clock. Nobody has entered—or left—during the time that's elapsed."
"I never supposed they had," remarked Brent. "The thing's been done in much cleverer fashion than that! As I said before, what we do know is that the murderer got to the Mayor's Parlour, and that he got away from it!"
Hawthwaite shook his head, with a puzzled expression overspreading his somewhat heavy and unimaginative features.
"Ay, but how?" he said. "How?"
"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.
"For suspecting anyone?" he exclaimed. "Good Lord, no, Mr. Brent! His Worship, poor man, wasn't exactly popular in the town—with a certain section, that is—but I couldn't believe that there's man or woman in the place would wish him harm! No, sir—in my opinion this is outside work!"
"Somewhat doubtful whether any outsider could obtain the apparently very accurate knowledge of Hathelsborough Moot Hall which the murderer of my cousin evidently possessed, isn't it?" suggested Brent. "I should say the guilty person is some one who knows the place extremely well!"
Before the superintendent could reply, his partly-open door was further opened, and a little, bustling, eager-faced man, who wore large spectacles and carried a pencil behind his right ear, looked in. Brent recognized him as another of the half-dozen Hathelsborough men whose acquaintance he had made on former visits—Peppermore, the hard-worked editor-reporter of the one local newspaper. Wallingford had introduced him to Peppermore in the smoking-room of the Chancellor Hotel, and Peppermore, who rarely got the chance of talking to London journalists, had been loquacious and ingratiating. His expressive eyebrows—prominent features of his somewhat odd countenance—went up now as he caught sight of Brent standing on the superintendent's hearth-rug. He came quickly into the room.
"Mr. Brent!" he exclaimed. "No idea you were here, sir. My profound sympathy, Mr. Brent! Dear, dear! what a truly
