POLICHINELLE
"Why, Ned," he asked gravely, "what has happened?"
"It is Samoval," was Tremayne's quiet answer. "He is quite dead."
He stood up as he spoke, and Sir Terence observed with terrible inward mirth that his tone had the frank and honest ring, his bearing the imperturbable ease which more than once before had imposed upon him as the outward signs of an easy conscience. This secretary of his was a cool scoundrel.
"Samoval, is it?" said Sir Terence, and went down on one knee beside the body to make a perfunctory examination. Then he looked up at the captain.
"And how did this happen?"
"Happen?" echoed Tremayne, realising that the question was being addressed particularly to himself. "That is what I am wondering.
I found him here in this condition."
"You found him here? Oh, you found him here in this condition!
Curious!" Over his shoulder he spoke to the butler: "Mullins, you had better call the guard." He picked up the slender weapon that lay beside Samoval. "A duelling sword!" Then he looked searchingly about him until his eyes caught the gleam of the other blade near the wall, where himself he had dropped it. "Ah!" he said, and went to pick it up. "Very odd!" He looked up at the balcony, over the parapet of which his wife was leaning. "Did you see anything, my dear?" he asked, and neither Tremayne nor she detected the faint note of wicked mockery in the question.
There was a moment's pause before she answered him, faltering:
"N-no. I saw nothing." Sir Terence's straining ears caught no faintest sound of the voice that had prompted her urgently from behind the curtained windows.
"How long have you been there?" he asked her.
"A - a moment only," she replied, again after a pause. "I - I thought I heard a cry, and - and I came to see what had happened."
Her voice shook with terror; but what she beheld would have been quite enough to account for that.
The guard filed in through the doors from the official quarters, a sergeant with a halbert in one hand and a lantern in the other, followed by four men, and lastly by Mullins. They halted and came to attention before Sir Terence. And almost at the same moment there was a sharp rattling knock on the wicket in the great closed gates through which Samoval had entered. Startled, but without showing any signs of it, Sir Terence bade Mullins go open, and in a general silence all waited to see who it was that came.
A tall man, bowing his shoulders to pass under the low lintel of that narrow door, stepped over the sill and into the courtyard. He wore a cocked hat, and as his great cavalry cloak fell open the yellow rays of the sergeant's lantern gleamed faintly on a British uniform. Presently, as he advanced into the quadrangle, he disclosed the aquiline features of Colquhoun Grant.
"Good-evening, General. Good-evening, Tremayne," he greeted one and the other. Then his eyes fell upon the body lying between them. "Samoval, eh? So I am not mistaken in seeking him here. I have had him under very close observation during the past day or two, and when one of my men brought me word tonight that he had left his place at Bispo on foot and alone, going along the upper Alcantara road, If had a notion that he might be coming to Monsanto and I followed. But I hardly expected to find this. How has it happened?"
"That is what I was just asking Tremayne," replied Sir Terence.
"Mullins discovered him here quite by chance with the body."
"Oh!" said Grant, and turned to the captain. "Was it you then - "
"I?" interrupted Tremayne with sudden violence. He seemed now to become aware for the first time of the gravity of his position.
"Certainly not, Colonel Grant. I heard a cry, and I came out to see what it was. I found Samoval here, already dead."
"I see," said Grant. "You were with Sir Terence, then, when this - "
"Nay," Sir Terence interrupted. "I have been alone since dinner, clearing up some arrears of work. I was in my study there when Mullins called me to tell me what he had discovered. It looks as if there had been a duel. Look at these swords." Then he turned to his secretary. "I think, Captain Tremayne," he said gravely, "that you had better report yourself under arrest to your colonel."
Tremayne stiffened suddenly. "Report myself under arrest?" he cried. "My God, Sir Terence, you don't believe that I - "
Sir Terence interrupted him. The voice in which he spoke was stern, almost sad; but his eyes gleamed with fiendish mockery the while. It was Polichinelle that spoke - Polichinelle that mocks what time he slays. "What were you doing here?" he asked, and it was like moving the checkmating piece.
Tremayne stood stricken and silent. He cast a desperate upward glance at the balcony overhead. The answer was so easy, but it would entail delivering Richard Butler to his death. Colonel Grant, following his upward glance, beheld Lady O'Moy for the first time.
He bowed, swept off his cocked hat, and "Perhaps her ladyship," he suggested to Sir Terence, "may have seen something."
"I have already asked her," replied O'Moy.
And then she herself was feverishly assuring Colonel Grant that she had seen nothing at all, that she had heard a cry and had come out on to the balcony to see what was happening.
"And was Captain Tremayne here when you came out?" asked O'Moy, the deadly jester.
"Ye-es," she faltered. "I was only a moment or two before yourself."
"You see?" said Sir Terence heavily to Grant, and Grant, with pursed lips, nodded, his eyes moving from O'Moy to Tremayne.
"But, Sir Terence," cried Tremayne, "I give you my word - I swear to you - that I know absolutely nothing of how Samoval met his death."
"What were you doing here?" O'Moy asked again, and this time the sinister, menacing note of derision vibrated clearly in the question.
