the case for the defence is practically complete."
"What, in Heaven's name, do you mean?" exclaimed Stopford, starting up.
"I mean that we can now prove when and where and how Miss Grant met her death. Come and sit down here, and I will explain. No, you needn't go away, Mr. Felton. We shall have to subpoena you. Perhaps," he continued, "we had better go over the facts and see what they suggest. And first we note the position of the body, lying with the feet close to the off-side door, showing that, when she fell, the deceased was sitting, or more probably standing, close to that door. Next there is this." He drew from his pocket a folded paper, which he opened, displaying a tiny blue disc. "It is one of the sequins with which her hat was trimmed, and I have in this envelope several more which I took from the hat itself.
"This single sequin I picked up on the rear end of the off side footboard, and its presence there makes it nearly certain that at some time Miss Grant had put her head out of the window on that side.
"The next item of evidence I obtained by dusting the margins of the off-side window with a light powder, which made visible a greasy impression three and a quarter inches long on the sharp corner of the right-hand jamb (right-hand from the inside, I mean).
"And now as to the evidence furnished by the body. The wound in the skull is behind and above the left ear, is roughly circular, and measures one inch and seven-sixteenths at most, and a ragged scalp-wound runs from it towards the left eye. On the right cheek is a linear contused wound three and a quarter inches long. There are no other injuries.
"Our next facts are furnished by this." He took up the horn and tapped it with his finger, while the solicitor and Mr. Felton stared at him in speechless wonder. "You notice it is a left horn, and you remember that it was highly sensitive. If you put your ear to it while I strain it, you will hear the grating of a fracture in the bony core. Now look at the pointed end, and you will see several deep scratches running lengthwise, and where those scratches end the diameter of the horn is, as you see by this calliper-gauge, one inch and seven-sixteenths. Covering the scratches is a dry blood-stain, and at the extreme tip is a small mass of a dried substance which Dr. Jervis and I have examined with the microscope and are satisfied is brain tissue."
"Good God!" exclaimed Stopford eagerly. "Do you mean to say—"
"Let us finish with the facts, Mr. Stopford," Thorndyke interrupted. "Now, if you look closely at that blood-stain, you will see a short piece of hair stuck to the horn, and through this lens you can make out the root-bulb. It is a golden hair, you notice, but near the root it is black, and our calliper-gauge shows us that the black portion is fourteen sixty-fourths of an inch long. Now, in this envelope are some hairs that I removed from the dead woman's head. They also are golden hairs, black at the roots, and when I measure the black portion I find it to be fourteen sixty-fourths of an inch long. Then, finally, there is this."
He turned the horn over, and pointed to a small patch of dried blood. Embedded in it was a blue sequin.
Mr. Stopford and the butcher both gazed at the horn in silent amazement; then the former drew a deep breath and looked up at Thorndyke.
"No doubt," said he, "you can explain this mystery, but for my part I am utterly bewildered, though you are filling me with hope."
"And yet the matter is quite simple," returned Thorndyke, "even with these few facts before us, which are only a selection from the body of evidence in our possession. But I will state my theory, and you shall judge." He rapidly sketched a rough plan on a sheet of paper, and continued: "These were the conditions when the train was approaching Woldhurst: Here was the passenger-coach, here was the burning rick, and here was a cattle-truck. This steer was in that truck. Now my hypothesis is that at that time Miss Grant was standing with her head out of the off-side window, watching the burning rick. Her wide hat, worn on the left side, hid from her view the cattle-truck which she was approaching, and then this is what happened." He sketched another plan to a larger scale. "One of the steers—this one—had thrust its long horn out through the bars. The point of that horn struck the deceased's head, driving her face violently against the corner of the window, and then, in disengaging, ploughed its way through the scalp, and suffered a fracture of its core from the violence of the wrench. This hypothesis is inherently probable, it fits all the facts, and those facts admit of no other explanation."
The solicitor sat for a moment as though dazed; then he rose impulsively and seized Thorndyke's hands. "I don't know what to say to you," he exclaimed huskily, "except that you have saved my brother's life, and for that may God reward you!"
The butcher rose from his chair with a slow grin.
"It seems to me," said he, "as if that ox-gall was what you might call a blind, eh, sir?"
And Thorndyke smiled an inscrutable smile.

When we returned to town on the following day we were a party of four, which included Mr. Harold Stopford. The verdict of "Death by misadventure," promptly returned by the coroner's jury, had been shortly followed by his release from custody, and he now sat with his brother and me, listening with rapt attention to Thorndyke's analysis of the case.
"So, you see," the latter concluded, "I had six possible theories of the cause of death worked out before I reached Halbury, and it only remained to select the one that fitted the facts. And when I had seen the cattle-truck, had picked up that sequin, had heard the description of the steers, and had seen the hat and the wounds, there was nothing left to do but the filling in of details."
"And you never doubted my innocence?" asked Harold Stopford.
Thorndyke smiled at his quondam client.
"Not after I had seen your colour-box and your sketch," said he, "to say nothing of the spike."
The Moabite Cipher
A large and motley crowd lined the pavements of Oxford Street as Thorndyke and I made our way leisurely eastward. Floral decorations and drooping bunting announced one of those functions inaugurated from time to time by a benevolent Government for the entertainment of fashionable loungers and the relief of distressed pickpockets. For a Russian Grand Duke, who had torn himself away, amidst valedictory explosions, from a loving if too demonstrative people, was to pass anon on his way to the Guildhall; and a British Prince, heroically indiscreet, was expected to occupy a seat in the ducal carriage.
Near Rathbone Place Thorndyke halted and drew my attention to a smart-looking man who stood lounging in a doorway, cigarette in hand.
"Our old friend Inspector Badger," said Thorndyke. "He seems mightily interested in that gentleman in the light overcoat. How d'ye do, Badger?" for at this moment the detective caught his eye and bowed. "Who is your friend?"
"That's what I want to know, sir," replied the inspector. "I've been shadowing him for the last half-hour, but I can't make him out, though I believe I've seen him somewhere. He don't look like a foreigner, but he has got something bulky in his pocket, so I must keep him in sight until the Duke is safely past. I wish," he added gloomily, "these beastly Russians would stop at home. They give us no end of trouble."
"Are you expecting any—occurrences, then?" asked Thorndyke.
"Bless you, sir," exclaimed Badger, "the whole route is lined with plain-clothes men. You see, it is known that several desperate characters
