An instant after there was the noise or knocking on the front door, dulled by the closed doors between. She knew that the rest of the household were in the upper parts of the house, but she could not have analysed the motive that made her go to the front door herself. On the doorstep stood a dumpy and dingy figure in black, which she recognized as the Roman Catholic priest, whose name was Brown. She knew him only slightly; but she liked him. He did not encourage her psychic views; quite the contrary; but he discouraged them as if they mattered and not as if they did not matter. It was not so much that he did not sympathize with her opinions, as that he did sympathize but did not agree. All this was in some sort of chaos in her mind as she found herself saying, without greeting, or waiting to hear his business:
"I'm so glad you've come. I've seen a ghost."
"There's no need to be distressed about that," he said. "It often happens. Most of the ghosts aren't ghosts, and the few that may be won't do you any harm. Was it any ghost in particular?"
"No," she admitted, with a vague feeling of relief, "it wasn't so much the thing itself as an atmosphere of awful decay, a sort of luminous ruin. It was a face. A face at the window. But it was pale and goggling, and looked like the picture of Judas."
"Well, some people do look like that," reflected the priest, "and I dare say they look in at windows, sometimes. May I come in and see where it happened?"
When she returned to the room with the visitor, however, other members of the family had assembled, and those of a less psychic habit had thought it convenient to light the lamps. In the presence of Mrs. Bankes, Father Brown assumed a more conventional civility, and apologized for his intrusion.
"I'm afraid it is taking a liberty with your house, Mrs. Bankes," he said. "But I think I can explain how the business happens to concern you. I was up at the Pulmans' place just now, when I was rung up and asked to come round here to meet a man who is coming to communicate something that may be of some moment to you. I should not have added myself to the party, only I am wanted, apparently, because I am a witness to what has happened up at Beechwood. In fact, it was I who had to give the alarm."
"What has happened?" repeated the lady.
"There has been a robbery up, at Beechwood House," said Father Brown, gravely; "a robbery, and what I fear is worse, Lady Pulman's jewels have gone; and her unfortunate secretary, Mr. Barnard, was picked up in the garden, having evidently been shot by the escaping burglar."
"That man," ejaculated the lady of the house. "I believe he was----"
She encountered the grave gaze of the priest, and her words suddenly went from her; she never knew why.
"I communicated with the police," he went on, "and with another authority interested in this case; and they say that even a superficial examination has revealed foot-prints and finger-prints and other indications of a well-known criminal."
At this point, the conference was for a moment disturbed, by the return of John Bankes, from what appeared to be an abortive expedition in the car. Old Smith seemed to have been a disappointing passenger, after all.
"Funked it, after all, at the last minute," he announced with noisy disgust. "Bolted off while I was looking at what I thought was a puncture. Last time I'll take one of these yokels----"
But his complaints received small attention in the general excitement that gathered round Father Brown and his news.
"Somebody will arrive in a moment," went on the priest, with the same air of weighty reserve, "who will relieve me of this responsibility. When I have confronted, you with him I shall have done my duty as a witness in a serious business. It only remains for me to say that a servant up at Beechwood House told me that she had seen a face at one of the windows----"
"I saw a face," said Opal, "at one of our windows."
"Oh, you are always seeing faces," said her brother John roughly.
"It is as well to see facts even if they are faces," said Father Brown equably, "and I think the face you saw----"
Another knock at the front door sounded through the house, and a minute afterwards the door of the room opened and another figure appeared. Devine half-rose from his chair at the sight of it.
It was a tall, erect figure, with a long, rather cadaverous face, ending in a formidable chin. The brow was rather bald, and the eyes bright and blue, which Devine had last seen obscured with a broad straw hat.
"Pray don't let anybody move," said the man called Carver, in clear and courteous tones. But to Devine's disturbed mind the courtesy had an ominous resemblance to that of a brigand who holds a company motionless with a pistol.
"Please sit down, Mr. Devine," said Carver; "and, with Mrs. Bankes's permission, I will follow your example. My presence here necessitates an explanation. I rather fancy you suspected me of being an eminent and distinguished burglar."
"I did," said Devine grimly.
"As you remarked," said Carver, "it is not always easy to know a wasp from a bee."
After a pause, he continued: "I can claim to be one of the more useful, though equally annoying, insects. I am a detective, and I have come down to investigate an alleged renewal of the activities of the criminal calling himself Michael Moonshine. Jewel robberies were his speciality; and there has just been one of them at Beechwood House, which, by all the technical tests, is obviously his work. Not only do the prints correspond, but you may possibly know that when he was last arrested, and it is believed on other occasions also, he wore a simple but effective disguise of a red beard and a pair of large horn-rimmed spectacles."
Opal Bankes leaned forward fiercely.
"That was it," she cried in excitement, "that was the face I saw, with great goggles and a red, ragged beard like Judas. I thought it was a ghost."
"That was also the ghost the servant at Beechwood saw," said Carver dryly.
He laid some papers and packages on the table, and began carefully to unfold them. "As I say," he continued, "I was sent down here to make inquiries about the criminal plans of this man, Moonshine. That is why I interested myself in bee-keeping and went to stay with Mr. Smith."
There was a silence, and then Devine started and spoke: "You don't seriously mean to say that nice old man----"
"Come, Mr. Devine," said Carver, with a smile, "you believed a beehive was only a hiding-place for me. Why shouldn't it be a hiding-place for him?"
Devine nodded gloomily, and the detective turned back to his papers. "Suspecting Smith, I wanted to get him out of the way and go through his belongings; so I took advantage of Mr. Bankes's kindness in giving him a joy ride. Searching his house, I found some curious things to be owned by an innocent old rustic interested only in bees. This is one of them."
From the unfolded paper he lifted a long, hairy object almost scarlet in colour--the sort of sham beard that is worn in theatricals.
Beside it lay an old pair of heavy horn-rimmed spectacles.
"But I also found something," continued Carver, "that more directly concerns this house, and must be my excuse for intruding to-night. I found a memorandum, with notes of the names and conjectural value of various pieces of jewellery in the neighbourhood. Immediately after the note of Lady Pulman's tiara was the mention of an emerald necklace belonging to Mrs. Bankes."
Mrs. Bankes, who had hitherto regarded the invasion of her house with an air of supercilious bewilderment, suddenly grew attentive. Her face suddenly looked ten years older and much more intelligent. But before she could speak the impetuous John had risen to his full height like a trumpeting elephant.
"And the tiara's gone already," he roared; "and the necklace--I'm going to see about that necklace!"
"Not a bad idea," said Carver, as the young man rushed from the room; "though, of course, we've been keeping our eyes open since we've been here. Well, it took me a little time to make out the memorandum, which was in cipher, and Father Brown's telephone message from the House came as I was near the end. I asked him to run round here first with the news, and I would follow; and so----"
His speech was sundered by a scream. Opal was standing up and pointing rigidly at the round window.
"There it is again!" she cried.
For a moment they all saw something--something that cleared the lady of the charges of lying and hysteria not uncommonly brought against her. Thrust out of the slate-blue darkness without, the face was pale, or, perhaps, blanched by pressure against the glass; and the great, glaring eyes, encircled as with rings, gave it rather the look of a great fish out of the dark-blue sea nosing at the port-hole of a ship. But the gills or fins of the fish were a coppery red; they were, in truth, fierce red whiskers and the upper part of a red beard. The next moment it had vanished.
Devine had taken a single stride towards the window when a shout resounded through the house, a shout that seemed to shake it. It seemed almost too deafening to be distinguishable as words; yet it was enough to stop Devine in his stride, and he knew what had happened.
