"It is merely the fragment of a letter. It is little better than an address. It is—— But you shall see it for yourself."
Old Broadbrim extended the paper, and the girl took it eagerly, but with some show of fear.
He watched her as she leaned forward and looked at the writing in the light of the dropjet.
Suddenly the young lady uttered a cry, and then turned upon the man-hunter with a frightened face absolutely colorless.
"It's from the same part of the world; I remember now!" she exclaimed. "The postmark on that letter was Perth. The whole thing comes back to me. The postman brought the letter to the house, and I carried it to his desk to await his coming home. It the same name—Perth. Where is it?"
"You mean in what part of Australia, miss?"
"Yes, yes."
"It is in West Australia, and beyond it lie the barren and death lands of the great island. But what is the name?"
"Merle Macray," spoke Nora, in a whisper. "What a strange name it is, and don't you see that the handwriting is that of one of my sex? And the line above the address—just look at it in the light of this murderous deed. 'Don't let him see sixty-four!' That means that the command to kill Custer Kipp comes from that far part of the globe. It makes it all the more terrible."
