When this spirit of the captain spoke in Valentin he was obeyed like a bugle. Dr. Simon went through to the armoury and routed out Ivan, the public detective’s private detective. Galloway went to the drawing-room and told the terrible news tactfully enough, so that by the time the company assembled there the ladies were already startled and already soothed. Meanwhile the good priest and the good atheist stood at the head and foot of the dead man motionless in the moonlight, like symbolic statues of their two philosophies of death.
Ivan, the confidential man with the scar and the moustaches, came out of the house like a cannon ball, and came racing across the lawn to Valentin like a dog to his master. His livid face was quite lively with the glow of this domestic detective story, and it was with almost unpleasant eagerness that he asked his master’s permission to examine the remains.
“Yes; look, if you like, Ivan,” said Valentin, “but don’t be long. We must go in and thrash this out in the house.”
Ivan lifted the head, and then almost let it drop.
“Why,” he gasped, “it’s—no, it isn’t; it can’t be. Do you know this man, sir?”
“No,” said Valentin indifferently; “we had better go inside.”
Between them they carried the corpse to a sofa in the study, and then all made their way to the drawing-room.
The detective sat down at a desk quietly, and even without hesitation; but his eye was the iron eye of a judge at assize. He made a few rapid notes upon paper in front of him, and then said shortly: “Is everybody here?”
“Not Mr. Brayne,” said the Duchess of Mont St. Michel, looking round.
“No,” said Lord Galloway in a hoarse, harsh voice. “And not Mr. Neil O’Brien, I fancy. I saw that gentleman walking in the garden when the corpse was still warm.”
“Ivan,” said the detective, “go and fetch Commandant O’Brien and Mr. Brayne. Mr. Brayne, I know, is finishing a cigar in the dining-room; Commandant O’Brien, I think, is walking up and down the conservatory. I am not sure.”
The faithful attendant flashed from the room, and before anyone could stir or speak Valentin went on with the same soldierly swiftness of exposition.
“Everyone here knows that a dead man has been found in the garden, his head cut clean from his body. Dr. Simon, you have examined it. Do you think that to cut a man’s throat like that would need great force? Or, perhaps, only a very sharp knife?”
“I should say that it could not be done with a knife at all,” said the pale doctor.
“Have you any thought,” resumed Valentin, “of a tool with which it could be done?”
“Speaking within modern probabilities, I really haven’t,” said the doctor, arching his painful brows. “It’s not easy to hack a neck through even clumsily, and this was a very clean cut. It could be done with a battle-axe or an old headsman’s axe, or an old two-handed sword.”
“But, good heavens!” cried the Duchess, almost in hysterics, “there aren’t any two-handed swords and battle-axes round here.”
Valentin was still busy with the paper in front of him. “Tell me,” he said, still writing rapidly, “could it have been done with a long French cavalry sabre?”
A low knocking came at the door, which, for some unreasonable reason, curdled everyone’s blood like the knocking in Macbeth. Amid that frozen silence Dr. Simon managed to say: “A sabre—yes, I suppose it could.”
“Thank you,” said Valentin. “Come in, Ivan.”
The confidential Ivan opened the door and ushered in Commandant Neil O’Brien, whom he had found at last pacing the garden again.
The Irish officer stood up disordered and defiant on the threshold. “What do you want with me?” he cried.
“Please sit down,” said Valentin in pleasant, level tones. “Why, you aren’t wearing your sword. Where is it?”
“I left it on the library table,” said O’Brien, his brogue deepening in his disturbed mood. “It was a nuisance, it was getting—”
“Ivan,” said Valentin, “please go and get the Commandant’s sword from the library.” Then, as the servant vanished, “Lord Galloway says he saw you leaving the garden just before he found the corpse. What were you doing in the garden?”
The Commandant flung himself recklessly into a chair. “Oh,” he cried in pure Irish, “admirin’ the moon. Communing with Nature, me bhoy.”
A heavy silence sank and endured, and at the end of it came again that trivial and terrible knocking. Ivan reappeared, carrying an empty steel scabbard. “This is all I can find,” he said.
“Put it on the table,” said Valentin, without looking up.
There was an inhuman silence in the room, like that sea of inhuman silence round the dock of the condemned murderer. The Duchess’s weak exclamations had long ago died away. Lord
