One choking cry he gave—smothered, inarticulate—and I found him slipping from my grip—being drawn out of the window—drawn to his death!

"Hold him, Guthrie!" I gasped hoarsely. "My God, he's going! Hold him!"

My friend writhed in our grasp, and I saw him stretch his arm upward. The crack of his revolver came, and he collapsed on to the floor, carrying me with him.

But as I fell I heard a scream above. Smith's revolver went hurtling through the air, and, hard upon it, went a black shape—flashing past the open window into the gulf of the night.

"The light! The light!" I cried.

Guthrie ran and turned on the light. Nayland Smith, his eyes starting from his head, his face swollen, lay plucking at a silken cord which showed tight about his throat.

"It was a Thug!" screamed Guthrie. "Get the rope off! He's choking!"

My hands a-twitch, I seized the strangling-cord.

"A knife! Quick!" I cried. "I have lost mine!"

Guthrie ran to the dressing-table and passed me an open penknife. I somehow forced the blade between the rope and Smith's swollen neck, and severed the deadly silken thing.
