He referred to his brother who had been foully done to death by one of the creatures of Dr. Fu-Manchu.

"It beats me how Mr. Smith got on the track!" he added.

"Pure inspiration!" murmured Nayland Smith, glancing aside from the siphon wherewith he now was busy. "The divine afflatus--and the same whereby Petrie solved the Zagazig cryptogram!"

"But," concluded Forsyth, "I am indebted to you for an opportunity of meeting the Chinese strangler, and sending him to join the Burmese knife expert!"

Such, then, were the episodes that led to the arrest of M. Samarkan, and my duty as narrator of these strange matters now bears me on to the morning when Nayland Smith was hastily summoned to the prison into which the villainous Greek had been cast.

We were shown immediately into the Governor's room and were invited by that much disturbed official to be seated. The news which he had to impart was sufficiently startling.

Samarkan was dead.

"I have Warder Morrison's statement here," said Colonel Warrington, "if you will be good enough to read it----"

Nayland Smith rose abruptly, and began to pace up and down the little office. Through the open window I had a glimpse of a stooping figure in convict garb, engaged in liming the flower-beds of the prison Governor's garden.

"I should like to see this Warder Morrison personally," snapped my friend.

"Very good," replied the Governor, pressing a bell-push placed close beside his table.

A man entered, to stand rigidly at attention just within the doorway.

"Send Morrison here," ordered Colonel Warrington.

The man saluted and withdrew. As the door was reclosed, the Colonel sat drumming his fingers upon the table, Nayland Smith walked restlessly about tugging at the lobe of his ear, and I absently watched the convict gardener pursuing his toils. Shortly, sounded a rap at the door, and--

"Come in," cried Colonel Warrington.

A man wearing warder's uniform appeared, saluted the Governor, and stood glancing uneasily from the Colonel to Smith. The latter had now ceased his perambulations, and, one elbow resting upon the mantelpiece, was staring at Morrison--his penetrating gray eyes as hard as steel. Colonel Warrington twisted his chair around, fixing his monocle more closely in its place. He had the wiry white mustache and fiery red face of the old-style Anglo-Indian officer.

"Morrison," he said, "Mr. Commissioner Nayland Smith has some questions to put to you."

The man's uneasiness palpably was growing by leaps and bounds. He was a tall and intelligent-looking fellow of military build, though spare for his height and of an unhealthy complexion. His eyes were curiously dull, and their pupils interested me, professionally, from the very moment of his entrance.

"You were in charge of the prisoner Samarkan?" began Smith harshly.

"Yes, sir," Morrison replied.

"Were you the first to learn of his death?"

"I was, sir. I looked through the grille in the door and saw him lying on the floor of the cell."

"What time was it?"

"Half-past four A.M."

"What did you do?"

"I went into the cell and then sent for the head warder."

"You realized at once that Samarkan was dead?"

"At once, yes."

"Were you surprised?"

Nayland Smith subtly changed the tone of his voice in asking the last question, and it was evident that the veiled significance of the words was not lost upon Morrison.

"Well, sir," he began, and cleared his throat nervously.

"Yes, or no!" snapped Smith.

Morrison still hesitated, and I saw his underlip twitch. Nayland Smith, taking two long strides, stood immediately in front of him, glaring grimly into his face.

"This is your chance," he said emphatically; "I shall not give you another. You had met Samarkan before?"

Morrison hung his head for a moment, clenching and unclenching his fists; then he looked up swiftly, and the light of a new resolution was in his eyes.

"I'll take the chance, sir," he said, speaking with some emotion, "and I hope, sir"--turning momentarily to Colonel Warrington--"that you'll be as lenient as you can; for I didn't know there was any harm in what I did."

"Don't expect any leniency from me!" cried the Colonel. "If there has been a breach of discipline there will be punishment, rely upon it!"

"I admit the breach of discipline," pursued the man doggedly; "but I want to say, here and now, that I've no more idea than anybody else how the----"

Smith snapped his fingers irritably.

"The facts--the facts!" he demanded. "What you _don't_ know cannot help us!"

"Well, sir," said Morrison, clearing his throat again, "when the prisoner, Samarkan, was admitted, and I put him safely into his cell, he told me that he suffered from heart trouble, that he'd had an attack when he was arrested and that he thought he was threatened with another, which might kill him----"

"One moment," interrupted Smith, "is this confirmed by the police officer who made the arrest?"

"It is, sir," replied Colonel Warrington, swinging his chair around and consulting some papers upon his table. "The prisoner was overcome by faintness when the officer showed him the warrant and asked to be given some cognac from the decanter which stood in his room. This was administered, and he then entered the cab which the officer had waiting. He was taken to Bow Street, remanded, and brought here in accordance with some one's instructions."

"_My instructions_" said Smith. "Go on, Morrison."

"He told me," continued Morrison more steadily, "that he suffered from something that sounded to me like apoplexy."

"Catalepsy!" I suggested, for I was beginning to see light.

"That's it, sir! He said he was afraid of being buried alive! He asked me, as a favor, if he should die in prison to go to a friend of his and get a syringe with which to inject some stuff that would do away with all chance of his coming to life again after burial."

"You had no right to talk to the prisoner!" roared Colonel Warrington.

"I know that, sir, but you'll admit that the circ.u.mstances were peculiar.

Anyway, he died in the night, sure enough, and from heart failure, according to the doctor. I managed to get a couple of hours leave in the evening, and I went and fetched the syringe and a little tube of yellow stuff."
