"But what steps did you take to apprehend the murderer?"

Paul Harley looked at him quietly.

"What steps should you have taken?" he asked.

Inspector Aylesbury cleared his throat again, and:

"I don't think I should have let my man slip through my fingers like that," he replied. "Why! by now he may be out of the county."

"Your theory is quite feasible," said Harley, tonelessly.

"You were actually on the spot when the shot was fired, you admit that it was fired within a hundred yards, yet you did nothing to apprehend the murderer."

"No," replied Harley, "I was ridiculously inactive. You see, I am a mere amateur, Inspector. For my future guidance I should be glad to know what the correct procedure would have been."

Inspector Aylesbury blew his nose.

"I know my job," he said. "If I had been called in there might have been a different tale to tell. But he was a foreigner, and he paid for his ignorance, poor fellow."

Paul Harley took out his pipe and began to load it in a deliberate and lazy manner.

Inspector Aylesbury turned his prominent eyes in my direction.

CHAPTER XIX

COMPLICATIONS

"I am afraid of this man Aylesbury," said Paul Harley. We sat in the deserted dining room. I had contributed my account of the evening's happenings, Dr. Rolleston had made his report, and Inspector Aylesbury was now examining the servants in the library. Harley and I had obtained his official permission to withdraw, and the physician was visiting Madame de Stamer, who lay in a state of utter prostration.

"What do you mean, Harley?"

"I mean that he will presently make some tragic blunder. Good G.o.d, Knox, to think that this man had sought my aid, and that I stood by idly whilst he walked out to his death. I shall never forgive myself." He banged the table with his fist. "Even now that these unknown fiends have achieved their object, I am helpless, helpless. There was not a wisp of smoke to guide me, Knox, and one man cannot search a county."

I sighed wearily.

"Do you know, Harley," I said, "I am thinking of a verse of Kipling's."

"I know!" he interrupted, almost savagely.

"A Snider squibbed in the jungle.

Somebody laughed and fled-"

"Oh, I know, Knox. I heard that d.a.m.nable laughter, too."

"My G.o.d," I whispered, "who was it? What was it? Where did it come from?"

"As well ask where the shot came from, Knox. Out amongst all those trees, with a house that might have been built for a sounding-board, who could presume to say where either came from? One thing we know, that the shot came from the south."

He leaned upon a corner of the table, staring at me intently.

"From the south?" I echoed.

Harley glanced in the direction of the open door.

"Presently," he said, "we shall have to tell Aylesbury everything that we know. After all, he represents the law; but unless we can get Inspector Wess.e.x down from Scotland Yard, I foresee a miscarriage of justice. Colonel Menendez lay on his face, and the line made by his rec.u.mbent body pointed almost directly toward-"

I nodded, watching him.

"I know, Harley-toward the Guest House."

Paul Harley inclined his head, grimly.

"The first light which we saw," he continued, "was in a window of the Guest House. It may have had no significance. Awakened by the sound of a rifle-shot near by, any one would naturally get up."

"And having decided to come downstairs and investigate," I continued, "would naturally light a lamp."

"Quite so." He stared at me very hard. "Yet," he said, "unless Mr. Colin Camber can produce an alibi I foresee a very stormy time for him."

"So do I, Harley. A deadly hatred existed between these two men, and probably this horrible deed was done on the spur of the moment. It is of his poor little girl-wife that I am thinking. As though her troubles were not heavy enough already."

"Yes," he agreed. "I am almost tempted to hold my tongue, Knox, until I have personally interviewed these people. But of course if our blundering friend directly questions me, I shall have no alternative. I shall have to answer him. His talent for examination, however, scarcely amounts to genius, so that we may not be called upon for further details at the moment. I wonder how I can induce him to requisition Scotland Yard?"

He rested his chin in his hand and stared down reflectively at the carpet. I thought that he looked very haggard, as he sat there in the early morning light, dressed as for dinner. There was something pathetic in the pose of his bowed head.

Leaning across, I placed my hand on his shoulder.

"Don't get despondent, old chap," I said. "You have not failed yet."

"Oh, but I have, Knox!" he cried, fiercely, "I have! He came to me for protection. Now he lies dead in his own house. Failed? I have failed utterly, miserably."

I turned aside as the door opened and Dr. Rolleston came in.

"Ah, gentlemen," he said, "I wanted to see you before leaving. I have just been to visit Madame de Stamer again."

"Yes," said Harley, eagerly; "how is she?"

Dr. Rolleston lighted a cigarette, frowning perplexedly the while.

"To be honest," he replied, "her condition puzzles me."

He walked across to the fireplace and dropped the match, staring at Harley with a curious expression.

"Has any one told her the truth?" he asked.

"You mean that Colonel Menendez is dead?"

"Yes," replied Dr. Rolleston. "I understood that no one had told her?"

"No one has done so to my knowledge," said Harley.
