Holmes dismissed the boy.

I would have said more, but Holmes forestalled me. Instead we saw the maid, Reynolds, who had waited at dinner. She had nothing to tell us except that she had heard recent noises in the house, but took them for mice. She had been here in old Miss Caston's time, and believed the old woman died of a bad heart, aggravated by superst.i.tious fear. Reynolds undertook to inform Holmes of this without hesitation. She also presented me with a full, if untrained, medical diagnosis, adding, "As a doctor, you will follow me, I am sure, sir."

Lastly Nettie Prince came in, the successor to Lucy, and now Miss Caston's personal maid. She had been at the house only a few months.

Nettie was decorous and at ease, treating Holmes, I thought, to his surprise, as some kind of elevated policeman.

"Is your mistress fair to you?" Holmes asked her at once.

"Yes, sir. Perfectly fair."

"You have no cause for complaint."

"None, sir. In my last employment the mistress had a temper. But Miss Caston stays cool."

"You are not fond of her, then?"

Nettie Prince raised her eyes. "I do not ask to love her, sir. Only to please her as best I can. She is appreciative of what I do, in her own way."

"Do you believe the tales of a curse on the Caston women?"

"I have heard stranger things."

"Have you."

"Miss Caston is not afraid of it, sir. I think besides she would be the match for any man, thief or murderer-even a ghost. Old Sir Hugh de Castone himself would have had to be wary of her."

"Why do you say that?"

"She talks very little of her past, but she made her way in the world with only her wits. She will not suffer a fool. And she knows a great deal."

"Yet she has sent for me."

"Yes, sir." Nettie Prince looked down. "She spoke of you, sir, and I understand you are a very important and clever gentleman."

"And yet."

Nettie said, "I am amazed, sir, at her, wanting you in. From all I know of Miss Caston, I would say she would sit up with a pistol or a dagger in her lap, and face anything out-alone!"

"Well, Watson," said Holmes, when we were once more by ourselves in the parlour.

"That last girl, Nettie Prince, seems to have the right of it. An admirable woman, Miss Caston, brave as a lioness."

"But also cold and selfish. Unsympathetic to and intolerant of her inferiors. Does anything else strike you?"

"An oddity in names, Holmes."

Holmes glanced my way. "Pray enlighten me."

"The letters in the snow, ENRV. And here we have a Nettie, a Reynolds and a Vine."

"The E?"

"Perhaps for Eleanor Caston herself."

"I see. And perhaps it strikes you too, Watson, the similarity between the names Castle and Caston? Or between Caston and Watson, each of which is almost an anagram of the other, with only the C and the W being different. Just as, for example, both your name and that of our own paragon, Mrs. Hudson, end in S.O.N."

"Holmes!"

"No, Watson, my dear fellow, you are being too complex. Think."

I thought, and shook my head.

"ENR," said Holmes, "I believe to be an abbreviation of the one name, Eleanor, where the E begins, the N centres, and the R finishes."

"But the V, Holmes."

"Not a V, Watson, a Roman five. A warning of the five dangerous days, or that Miss Caston will be the fifth victim of the Gall. Just as the number five is written in her study, where I should now like to inspect it."

Miss Caston had not gone to bed. This was not to be wondered at, yet she asked us nothing when she appeared in the upper corridor, where now the gas burned low.

"The room is here," she said, and opened a door. "A moment, while I light a lamp."

When she moved forward and struck the match, her elegant figure was outlined on the light. As she raised the lamp, a bright blue flash on the forefinger of her right hand showed a ring. It was a square cut gem, which I took at first for a pale sapphire.

"There, Mr. Holmes, Doctor. Do you see?"

The number was written in red, and quite large, above the height of a man, on the old plaster of the wall which, in most other areas, was hidden by shelves of books.

"Quite so." Holmes went forward, looked about, and took hold of a librarian's steps, kept no doubt so that Miss Caston could reach the higher book shelves. Standing up on the steps, Holmes craned close, and inspected the number. "Would you bring the lamp nearer. Thank you. Why, Miss Caston, what an exquisite ring."

"Yes, it is. It was my aunt's and too big for me, but in London today it was made to fit. A blue topaz. I am often fascinated, Mr. Holmes, by those things which are reckoned to be one thing, but are, in reality, another."

"Where are you, Watson?" asked Holmes. I duly approached. "Look at this number." I obeyed. The five was very carefully drawn, I thought, despite its size, yet in some places the edges had run, giving it a th.o.r.n.y, b.l.o.o.d.y look. Holmes said no more, however, and descended from the steps.

"Is it paint, Holmes?"

"Ink, I believe."

Miss Caston a.s.sented. She pointed to a bottle standing on her desk, among the books and papers there. "My own ink. And the instrument too-this paper knife."

"Yes. The stain is still on it. And here is another stain, on the blotting paper, where it was laid down."

Holmes crossed the room, and pulled aside one of the velvet curtains. Outside the night had again given way to snow. Opening the window, he leaned forth into the fluttering darkness. "The ivy is torn somewhat on the wall." He leaned out yet further. Snow fell past him, and dappled the floor. "But, curiously, not further down." He now craned upwards and the lamplight caught his face, hard as ivory, the eyes gleaming. "It is possible the intruder came down from the roof rather than up from the garden below. The bough of a tree almost touches the leads just there. But it is very thin."

"The man must be an acrobat," I exclaimed.

Holmes drew back into the room. He said, "Or admirably bold."

Miss Caston seemed pale. She stared at the window until the curtain was closed again. The room was very silent, so that the ticking of a clock on the mantle seemed loud.

Holmes spoke abruptly. "And now to bed. Tomorrow, Miss Caston, there will be much to do."

Her face to me seemed suddenly desolate. As Holmes walked from the room, I said to her, "Rest as well as you can, Miss Caston. You are in the best of hands."

"I know it, Doctor. Tomorrow, then."

4.

The next morning, directly after breakfast, Holmes dispatched me to investigate the hamlet of Crowby. I had not seen Miss Caston; it seemed she was a late riser. Holmes, abroad unusually early, meanwhile wished to look at the bedchamber of the deceased elder Miss Caston. He later reported this was ornate but ordinary, equipped with swagged curtains and a bell-rope by the fire.

As I set out, not, I admit, in the best of humours, I noted that the sinister letters and the Roman number five had been obliterated from the ground below the terrace by a night's snow.

Elsewhere the heavy fall had settled, but not frozen, and in fact I had a pleasing and bracing walk. Among the beech coppices I spied pheasant, and on the holly, red berries gleamed.

Crowby was a sleepy spot, comprising two or three scattered cl.u.s.ters of houses, some quite fine, a lane or two, and an old ruin of a tower, where birds were nesting. There was neither a church nor an inn, the only public facility being a stone trough for the convenience of horses.

Vine's people lived in a small place nearby, but since Holmes had not suggested I look for it, or accost them, I went round the lanes and returned.

My spirits were quite high from the refreshing air, by the time I came back among the fields. Keeping to the footpath, I looked all about. It was a peaceful winter scene, with nothing abnormal or alarming in it.

When I came in sight of the house, I had the same impression. The building looked gracious, set in the white of the snow, the chimneys smoking splendidly.

Indoors, I found Vine, Reynolds and Nettie engaged in decorating the dining room with fresh-cut holly, while a tree stood ready to be dressed.

Holmes and Miss Caston were in the side parlour and I hesitated a moment before entering. A fire blazed on the parlour hearth, and a coffee pot steamed on the table. Holmes was speaking of a former case, affably and at some length. The lady sat rapt, now and then asking a sensible question.

Seeing me, however, Holmes got up and led me in.

"I have been regaling Miss Caston with an old history of ours, Watson. It turns out she has never read your account of it, though nothing else seems to have escaped her."

We pa.s.sed an enjoyable couple of hours before luncheon. I thought I had seldom seen Holmes so unlike himself in company, so relaxed and amenable. Miss Caston cast a powerful spell, if even he was subject to it. But presently, when he and I were alone, he changed his face at once, like a mask.

"Watson, I believe this interesting house is no less than a rat-trap, and we are all the rats in it."

"For G.o.d's sake, Holmes, what do you mean?"

"A plot is afoot," he said, "we must on no account show full knowledge of."

"Then she is in great danger?" I asked.

He glanced at me and said, coldly, "Oh, yes, my dear Watson. I do believe she is. We are dealing with high villainy here. Be on guard. Be ready. For now, I can tell you nothing else. Except that I have looked at the elder Miss Caston's papers myself, and made an obvious discovery."

"Which is?"

"The warning or threatening letter which was sent my client had all its words cut from various correspondence kept here. I have traced every word, save one. No doubt I would find that if I persisted. They were part of bills and letters, one of which was written in the early seventeenth century. Our enemy effaced them without a care. One other incidental. The footman, Vine, resents the dismissal of his sweetheart, Lucy, who was Miss Caston's former maid."

"His sweetheart?"

"Yes, Watson. You will remember how Vine spoke of his employer, saying that she was a hard mistress."

"But surely that was because she would not let him go off for Christmas."

"That too, no doubt. But when he mentioned her hardness, it was in the past tense, and in the same breath as Lucy's dismissal. He declared he 'should have left when Lucy did.'"

"She was not dismissed, Holmes. She went of her own accord."

"No. During our morning's friendly conversation, I put it to Miss Caston that she had perhaps sent Lucy away due to some misconduct with Vine. Our client did not attempt to deceive me on this. She said at once there had been trouble of that sort."

"That then furnishes Vine and Lucy with a strong reason for malice."

"Perhaps it does."

"Did she say why she had not told you this before?"

"Miss Caston said she herself did not think either Lucy or Vine had the wit for a game of this sort. Besides, she had not wanted to blacken the girl's character. Indeed, I understand she gave Lucy an excellent reference. Miss Caston expressed to me the opinion that Lucy had only been foolish and too ardent in love. She would be perfectly useful in another household."

"This is all very like her. She is a generous and intelligent woman."

Reynolds alone attended to us at lunch. The hall was by now nicely decked with boughs of holly. Miss Caston announced she would dress the tree herself in the afternoon. This she did, a.s.sisted by myself. Holmes moodily went off about his investigations.

My conversation with her was light. I felt I should do my part and try to cheer her, and she seemed glad to put dark thoughts aside. By the time tea was served, the tree had been hung with small gold and silver baubles, and the candles were in place. Miss Caston lit them just before dinner. It was a pretty sight.

That night too, Mrs. Castle had excelled. We dined royally on pheasant, with two or three ancient and dusty bottles to add zest.

Later, when Miss Caston made to leave us, Holmes asked her to remain.

"Then, I will, Mr. Holmes, but please do smoke. I have no objection to cigars. I like their smell. I think many women are of my mind, and sorry to be excluded."

The servants had withdrawn, Vine too, having noisily seen to the fire. The candles on the tree glittered. Nothing seemed further from this old, comfortable, festive room than our task.

"Miss Caston," said Holmes, regarding her keenly through the blue smoke, "the time has come when we must talk most gravely."

She took up her gla.s.s, and sipped the wine, through which the firelight shone in a crimson dart. "You find me attentive, Mr. Holmes."

"Then I will say at once what I think you know. The author of these quaint events is probably in this house."

She looked at him. "You say that I know this?"

"Were you not suspicious of it?"

"You are not intending to say that after all I believe Sir Hugh de Castone haunts me?"
