Holmes turned to his desk and, unlocking it, drew out a small case-book, which he consulted.

“Farintosh,” said he. “Ah yes, I recall the case; it was concerned with an opal tiara. I think it was before your time, Watson. I can only say, madam, that I shall be happy to devote the same care to your case as I did to that of your friend. As to reward, my profession is its own reward; but you are at liberty to defray whatever expenses I may be put to, at the time which suits you best. And now I beg that you will lay before us everything that may help us in forming an opinion upon the matter.”

“Alas!” replied our visitor, “the very horror of my situation lies in the fact that my fears are so vague, and my suspicions depend so entirely upon small points, which might seem trivial to another, that even he to whom of all others I have a right to look for help and advice looks upon all that I tell him about it as the fancies of a nervous woman. He does not say so, but I can read it from his soothing answers and averted eyes. But I have heard, Mr. Holmes, that you can see deeply into the manifold wickedness of the human heart. You may advise me how to walk amid amid the dangers which encompass me.”

“I am all attention, madam.”

“My name is Helen Stoner, and I am living with my stepfather, who is the last survivor of one of the oldest Saxon families in England, the Roylotts of Stoke Moran, on the western border of Surrey.”

Holmes nodded his head. “The name is familiar to me,” said he.

“The family was at one time among the richest in England, and the estates extended over the borders into Berkshire in the north, and Hampshire in the west. In the last century, however, four successive heirs were of a dissolute and wasteful disposition, and the family ruin was eventually completed by a gambler in the days of the Regency. Nothing was left save a few acres of ground, and the two-hundred-year-old house, which is itself crushed under a heavy mortgage. The last squire dragged out his existence there, living the horrible life of an aristocratic pauper; but his only son, my stepfather, seeing that he must adapt himself to the new conditions, obtained an advance from a relative, which enabled him to take a medical degree and went out to Calcutta, where, by his professional skill and his force of character, he established a large practice. In a fit of anger, however, caused by some robberies which had been perpetrated in the house, he beat his native butler to death and narrowly escaped a capital sentence. As it was, he suffered a long term of imprisonment and afterwards returned to England a morose and disappointed man.

“When Dr. Roylott was in India he married my mother, Mrs. Stoner, the young widow of Major-General Stoner, of the Bengal Artillery. My sister Julia and I were twins, and we were only two years old at the time of my mother’s re-marriage. She had a considerable sum of money — not less than 1000 pounds a year — and this she bequeathed to Dr. Roylott entirely while we resided with him, with a provision that a certain annual sum should be allowed to each of us in the event of our marriage. Shortly after our return to England my mother died — she was killed eight years ago in a railway accident near Crewe. Dr. Roylott then abandoned his attempts to establish himself in practice in London and took us to live with him in the old ancestral house at Stoke Moran. The money which my mother had left was enough for all our wants, and there seemed to be no obstacle to our happiness.

It was a sporting chance. Aaron packed his bag and got a passport, and wrote to Lilly to say he would join him, as invited, at Sir William Franks’. He hoped Lilly’s answer would arrive before he left London. But it didn’t.

Therefore behold our hero alighting at Novara, two hours late, on a wet, dark evening. He hoped Lilly would be there: but nobody. With some slight dismay he faced the big, crowded station. The stream of people carried him automatically through the barrier, a porter having seized his bag, and volleyed various unintelligible questions at him. Aaron understood not one word. So he just wandered after the blue blouse of the porter.

The porter deposited the bag on the steps of the station front, fired off more questions and gesticulated into the half–illuminated space of darkness outside the station. Aaron decided it meant a cab, so he nodded and said “Yes.” But there were no cabs. So once more the blue– bloused porter slung the big bag and the little bag on the strap over his shoulder, and they plunged into the night, towards some lights and a sort of theatre place.

One carriage stood there in the rain—yes, and it was free.

“Keb? Yes—orright—sir. Whe’to? Where you go? Sir William Franks? Yes, I know. Long way go—go long way. Sir William Franks.”

The cabman spattered his few words of English. Aaron gave the porter an English shilling. The porter let the coin lie in the middle of his palm, as if it were a live beetle, and darted to the light of the carriage to examine the beast, exclaiming volubly. The cabman, wild with interest, peered down from the box into the palm of the porter, and carried on an impassioned dialogue. Aaron stood with one foot on the step.

“What you give—he? One franc?” asked the driver.

“A shilling,” said Aaron.

“One sheeling. Yes. I know that. One sheeling English”—and the driver went off into impassioned exclamations in Torinese. The porter, still muttering and holding his hand as if the coin might sting him, filtered away.

“Orright. He know—sheeling—orright. English moneys, eh? Yes, he know. You get up, sir.”

And away went Aaron, under the hood of the carriage, clattering down the wide darkness of Novara, over a bridge apparently, past huge rain– wet statues, and through more rainy, half–lit streets.

They stopped at last outside a sort of park wall with trees above. The big gates were just beyond.

“Sir William Franks—there.” In a mixture of Italian and English the driver told Aaron to get down and ring the bell on the right. Aaron got down and in the darkness was able to read the name on the plate.

“How much?” said Aaron to the driver.

“Ten franc,” said the fat driver.

But it was his turn now to screw down and scrutinise the pink ten– shilling note. He waved it in his hand.

“Not good, eh? Not good moneys?”

“Yes,” said Aaron, rather indignantly. “Good English money. Ten shillings. Better than ten francs, a good deal. Better—better—”
