Chapter V

“Where did I get hold upon the clue?” asked Moris Klaw, when he, Haufmann, and I sat, in the gray dawn, waiting for the police to come and take away the body of Costa. “It was from the brain of Ottley! His poor mind”--he waved long hands circularly in the air--“goes round and round about the thing that happened to him on the balcony.”

“And what was that?” demanded Haufmann, eagerly. “Same as happened to me?”

“It was something--something that his knowledge of strange things tells him is venomous--which struck his wrist as he raised his revolver! What did he do? I can tell you; because he is doing it over and over again in his poor feverish mind. He clapped to the injured wrist the barrel of his revolver and fired! Then, swooning, he toppled over and fell among the bushes. The wound that so had puzzled all becomes explained. It was self-inflicted--a precaution--a cauterizing; and it saved his life. For I saw Sir Bartram Vane to-day and he had spoken with the other doctor on the telephone. The new treatment succeeds.”

“I am still in the dark!” confessed Haufmann.

“Yes?” rumbled Moris Klaw. “So? Why do I go to Brighton? I go to ask Miss Greta what Ottley would have asked her.”

“And that is?”

“What she feared that made her so very anxious to get you away from your home. To me she admitted that she had received from the man Costa impassioned appeals, such as, foolish girl, she had been afraid to show to you--her father!”

“Good heavens! the scamp!”

“The _canaille!_ But no matter, he is dead _canaille!_ After you got the brother hanged, this Corpus Chris (it was Fate that named him!) sent to your daughter a mad letter, swearing that if she does not fly with him, he will kill you if he has to follow you around the world! Yes, he was insane, I fancy; I think so. But he was a man of very great culture. He held a Cambridge degree! You did not know? I thought not. He tracked you to Europe and right to this house. Its history he learned in some way and used for his own ends. Probably, too, he had no opportunity of getting at you otherwise, without leaving behind a clue or being seen and pursued.”

Moris Klaw picked up an Indian bow which lay upon the floor beside him.

“A bow of the Sioux pattern,” he rumbled, impressively.

He stooped again, picking up a small arrow to which a length of thin black twine was attached.

“One standing on the balcony in the moonlight,” he continued, “what a certain mark if the wind be not too high! And you will remember that on gently blowing nights the whispering came!”

He raised the point of the arrow. It was encrusted in some black, shining substance. Moris Klaw lowered his voice.

“_Curari!_” he said, hoarsely, “the ancient arrow poison of the South American tribes! This small arrow would make only a tiny wound, and it could be drawn back again by means of the twine attached. Costa, of course, mistook Ottley for you, Mr. Haufmann. Ah, a clever fellow! I spent three evenings up the second tree in the avenue waiting for him. I need not have shot him if you had followed my instructions and not come out on the balcony. We could have captured him alive!”

“I’m not crying about it!” said Haufmann.

“Neither do I weep,” rumbled Moris Klaw, and bathed his face with perfume. “But I loathe it, this _curari_--it smells of death. Ah! the _canaille!_”
