This was undoubtedly true, as Colwyn had observed during his former visit to the inn. The deaf waiter was, to all intents and purposes, the real manager of the inn, leaving the innkeeper free to pursue his solitary life while he attended to the bar and the cellar, helped Ann with the work, and waited on infrequent travellers. Doubtless the arrangement suited both, though it could not have been profitable to either, for there was little more than a bare living for one in such a place.

Looking up suddenly from his plate, Colwyn caught the waiter's black eyes fixed on him in a keen penetrating gaze. Meeting the detective's eyes, Charles instantly lowered his own. But for the latter action Colwyn would have thought nothing of the incident, for he was aware that Charles, on account of his deafness, had to watch the lips of people he was serving in order to read their lips. But if Charles had been merely watching for him to speak he would not have felt impelled to avert his gaze when detected. The sudden lowering of his eyes was the swift unconscious action of a man taken by surprise. The detective realised that Charles did not accept the reason he had given to account for his second visit to the inn. Charles evidently suspected that that reason masked some ulterior motive.

Colwyn finished his dinner and produced his cigar-case. Selecting a cigar, he lit it with a match from the box Peggy had given him that day.

"Have you ever seen this box before, Charles?" he said, placing the box on the table.

The waiter picked up the little silver and enamel box and examined it attentively.

"I have, sir," he said, handing it back. "It is Mr. Penreath's."

"How do you recognise it?"

"By the letters in enamel, sir. I noticed them that night at the dinner table, when I was holding Mr. Penreath's candlestick while he lit it with a match from that box."

"Did he put it back in his pocket after lighting the candle?"

"Yes, sir; into his vest pocket."

"It was picked up in Mr. Glenthorpe's room after the murder was committed. A strong clue, Charles! Many a man has been hanged on less."

"No doubt, sir."

The waiter, balancing a tray on his deformed arm, proceeded to clear the table. When he had completed his task he asked the detective if he needed him any more, because if he did not it was time for him to go into the bar. On Colwyn saying that he needed nothing further he noiselessly withdrew, steadying the loaded tray with his sound hand.

Colwyn spent the evening sitting by the fire, smoking. It was fortunate he had plenty to think about, for the inn did not offer any resources in the way of reading to occupy the mind of the chance visitor to its roof. There were a few books in the recess by the fireplace, but they consisted of bound volumes of The Norfolk Sporting Gazette from 1860 to 1870, with an odd volume on Fishing on the Broads and an obsolete Farmers' Annual. The past occupants of the inn had evidently been keen sportsmen, for there were specimens of stuffed fowl and fish ranged in gla.s.s cases around the walls, and two old rusty fowling pieces and a fishing rod hung suspended near the ceiling.

Shortly after nine o'clock the innkeeper entered the room with a candlestick, which he placed on the table. He explained that it was his custom to go upstairs early, in order to sit with his mother for a little while before he retired. The poor soul looked for it, he said, and grew restless if he was late.

"Who is sitting with her at present?" inquired the detective.

"My daughter, sir. She always waits till I go up."

"You never leave her alone, then?"

"Only at night-time, sir. The doctor told me she could be safely left at night. She sleeps fairly well, considering, though when there's wild weather I always go in to her. The sound of the wind shrieking across the marshes from the sea excites her, and we get a lot of that sort of weather on the Norfolk coast, particularly in the winter months. I wish I could afford to have her better looked after, but I cannot, and that's the long and short of it."

"Things are pretty bad with you, Benson?"

"Very bad, indeed, sir. It keeps me awake at night, wondering where it's all going to end. However, I don't want to burden you with my troubles-I suppose we all have our own to bear. I merely came in to bring your candlestick, and to ask you if there is anything you want before I go to bed. Charles is gone to his room, but Ann is still up."

"Tell Ann she need not sit up on my account. I need nothing further, and I can find my way to my room. Is it ready yet?"

"Quite, sir. Ann has just been up there, putting on some fresh sheets. Perhaps you wouldn't mind turning off the gas at the meter as you go up-it is just underneath the stairs. If you would not mind the trouble Ann could then go to bed. We keep early hours here, as a rule. There is nothing to sit up for."

"I'll turn off the gas-I know where the meter is. How is it, Benson, that the gas is laid on in only two of the rooms upstairs-the rooms Mr. Glenthorpe used to occupy? It would have been an easy matter to lay it on to the adjoining rooms, once the pipes had been taken upstairs."

"That's quite true, sir, but the gas was taken upstairs on Mr. Glenthorpe's account, shortly after he came here. He thought he would like it, and he paid the bill for having it fixed. But after it was laid on he rarely used it. He said he found the gaslight trying for his eyes when he wanted to read in bed, so he got a reading lamp."

"And yet the gas tap was partly turned on in his room the morning after the murder," remarked Colwyn meditatively.

"Perhaps the murderer turned it on," suggested the innkeeper in a low tone.

But there was a slight tremor in his voice that did not escape the keen ears of the detective.

"That is possible, but the point was not cleared up at the trial; it probably never will be now," he replied, eyeing the innkeeper attentively. "And the incandescent burner was broken too. Have you had a new burner attached, Benson?"

"No, sir. The room has never been used since."

"It's a queer thing about that broken burner. That's another point in this case that was not cleared up at the trial. Who do you think broke it?"

"How should I know, sir?" His bird's eyes, in their troubled shadow, turned uneasily from the detective's glance.

"Nevertheless, you can hazard an opinion. Why not? The case is over and done with now, and Penreath-or Ronald, as he called himself-is condemned to death. So who do you think broke that burner, Benson?"

"Who else but the murderer, sir?"

"That's the police theory, I know, but I doubt whether Penreath was tall enough to strike it with his head. It's more than six feet from the ground." The detective threw a critical glance over the innkeeper's figure as though he were measuring his height with his eye. "You are well over six feet, Benson-you might have done it."

It was a chance shot, but the effect was remarkable. The innkeeper swung his small head on the top of his long neck in the direction of the detective, with a strange gesture, like a pinioned eagle twisting in a trap.

"What makes you say that!" he cried, and his voice had a new and strident note. "I had nothing whatever to do with it."

"What do you mean?" replied the detective sternly. "What do you suppose I am suggesting?"

"I beg your pardon, sir," replied the other. "The fact is I have not been myself for some time past."

His voice broke off in an odd tremor, and Colwyn noticed that the long thin hand he stretched out, as though to deprecate his previous violence, was shaking violently.

"What's the matter with you, man?" The detective eyed him keenly. "Your nerve has gone."

"I know it has, sir. What happened in this house a fortnight ago upset me terribly, and I haven't got over it yet. I have other troubles as well-private troubles. I've had to sit up with mother a good deal lately."

"You'd better take a few doses of bromide," said the detective brusquely. "A man with your nerves should not live in a place like this. You had better go to bed now. Good night."

"Good night, sir." The innkeeper hurried out of the room without another word.

Colwyn sat by the fire for some time longer pondering over this unexpected incident, until the kitchen clock chiming eleven warned him to go to bed. He turned off the gas at the meter underneath the stairs as Benson had requested. When he reached the room in which Mr. Glenthorpe had been murdered, he paused outside the door, and turned the handle. The door was locked.

As he was about to enter the adjoining bedroom which had been allotted to him, a slender pencil of light pierced the darkness of the pa.s.sage leading off the one in which he stood. As he watched the gleam grew brighter and broader; somebody was walking along the other pa.s.sage. A moment later the innkeeper's daughter came into view, carrying a candle. She advanced quickly to where the detective was standing.

"I heard you coming upstairs," she explained, in a whisper. "I have been waiting and listening at my door. I wanted to see you, but it is difficult for me to do so without the others knowing. So I thought I would wait. I wanted to let you know that if you wish to see me at any time-if you need me to do anything-perhaps you would put a note under my door, and I could meet you down by the breakwater at any time you appoint. n.o.body would see us there."

Colwyn nodded approvingly. Decidedly this girl was not lacking in resource and intelligence.

"I am so glad you are here," she went on earnestly. "I was afraid, after I left you to-day, that you might change your mind. I waited at one of the upstairs windows all the afternoon till I saw you coming. You will save him, won't you?"

She looked up at him with a faint smile, which, slight as it was, gave her face a new rare beauty.
