Delaney, with drawn gun and wild of eyes, burst through the tapestries and brought up with a dizzy lurch before the body of Cuthbert Morphy. He stammered and glared downward. He swung his heavy chin and stared at Loris and Nichols in the gloom of the further curtains. He clapped Drew on the shoulder with a heavy hand.

“Had to shoot him, eh, Chief? What’d he try? What—you got your foot on?”

“An electric pistol,” said Drew, with a grim smile distending his olive-hued lips. “An infernal machine, Delaney. I hope it isn’t a repeater. Cut that wire! Both wires! Get your knife out and cut through them, quick! I won’t take any chances.”

The big operative pocketed his revolver with a back swing of his right hand, brought it forward empty and ran it down his trouser pocket. He brought out a buck-horn jack-knife, pried it open, stooped and slashed through the two silk cords holding the receiver to the bottom of the transmitter which had fallen from the bracket.

Loris swayed with supple limbs. She raised her hands and pressed her unjeweled fingers against her face. She sobbed once, then turned and threw herself upon Nichols’ drab shoulder. “Harry,” she cried. “Oh, Harry—what happened? I didn’t see what happened!”

The captain glided an arm about her waist and half-carried, half-led her to a couch in the reading-room. “Rest here a minute,” he said, leaning down. “Be cool and as brave as you can. The trouble-man won’t trouble you any longer. He took his own medicine!”

Nichols returned to the sitting room in time to hear Drew exclaim, after Delaney had reached down and lifted the receiver, “The case is closed! This closes it with a bang! Give me that electric pistol, Delaney!”

The operative handed it over. “Get a big rug,” ordered Drew with sudden thought. “Cover that fellow over till we call the Central Office men and the coroner. I want to examine this receiver.”

“Right here on this little table would be a good place,” suggested Nichols, lifting off a handful of ivory ornaments and depositing them on top of a glass case. “I’ll spread a paper here. I’d like to see what’s inside that thing myself.”

“Do you know anything about electricity or telephony?” asked Drew, as he turned the hard-rubber receiver in his hand and stared at the listening end.
