“Dead?” she said intensely. “Guy Markenmore! Dead! It’s a lie!”

“Unfortunately, ma’am, it’s the strict truth,” retorted Chilford, as if a little nettled, and not a little scornful. “Mr. Guy Markenmore was found dead this morning, on the way between here and Mitbourne, and there’s no doubt that he was murdered.”

Mrs. Tretheroe gasped and started back against the big table that filled the centre of the room. Leaning heavily against it she lifted a hand towards her throat, as if something began to choke her. Her eyes, growing wild and desperate, fixed themselves on one face after another; finally they rested on Harborough, who was watching her intently. And then, with a cry that was half a scream, she lifted her hand still higher, pointing at him.

“Murdered?” she said. “Guy!—murdered? Then—then—there’s the man who murdered him!—I know it! Dare to say you didn’t, John Harborough!—you know you did! You threatened—seven years ago—to kill him whenever, wherever, you and he next met—and now—now—you’ve done it! Guy?—dead?—I—oh, God—I—I promised—last night—only a few hours ago—to—to marry him! We—Valencia!—we were going to be married—at once!”

“Now she is fainting!” muttered Mr. Fransemmery. “Good God!—what revelations!”

He started forward as Mrs. Tretheroe, with a sharp moan, slid heavily to the ground; with the help of Chilford and Valencia he got her out of the room, and sent Braxfield for the housekeeper. Leaving her and Valencia with Mrs. Tretheroe, he and Chilford went back to the other three men. The Chief Constable, his hands behind him, was leaning against the big mantelpiece; Harborough, very white, faced him from the other side of the table; Harry Markenmore stood a little way off, glancing doubtfully from one to the other.

“An awkward—but a decidedly definite accusation, Mr. Harborough,” the Chief Constable was saying. “She seemed to have no hesitation in making it!”

“You saw that she made it in a moment of intense excitement,” said Harborough. “And of—of grief.”

“It’s precisely in these moments—in my experience—that truth gets blurted out,” observed the Chief Constable drily. “However, as she said it before the lot of us, perhaps you’ll tell me something for your own sake. Did you ever make such a threat as that she spoke of?—did you ever threaten to kill Guy Markenmore, whenever and wherever you next met?”

Chilford gave a dry, deprecatory cough.
