"This is your doing?" he cried.
"It is my doing," Wingate admitted, with his eyes still fixed upon the other's face.
Dredlinton stumbled to the fireplace, found the bell and pressed it violently. A gleam of reassurance came to him.
"My servants shall hear you repeat that!" he exclaimed. "I will have them all in to witness your confession. You are pleading guilty to a crime! I shall send out for the police! I shall hand you over from here!"
"Not a bad idea," Wingate acknowledged. "By the by, though," he added, a moment or two later, "your servants don't seem in a great hurry to answer that bell."
Dredlinton pressed it more violently than ever. By listening intently both men could hear its faraway summons. But nothing happened. The house itself seemed empty. There was not even the sound of a footfall.
"You will really have to change your servants," Wingate continued. "Fancy not answering a bell! They must hear it pealing away. Still, you have the telephone. Why not ring up Scotland Yard direct?"
Dredlinton, dazed now with terror, took his fingers from the bell and snatched up the telephone receiver. All the time his eyes were riveted upon his companion's, their weak depths filled with a nameless horror.
"Quick!" he shouted down the receiver. "Scotland Yard! Put me straight through to Scotland Yard!—Can you hear me, Exchange? I am Lord Dredlinton, 1887 Mayfair. If I am cut off, ring through to Scotland Yard yourself. Tell them I am in danger of my life! Tell them to rush here at once!"
"Yes, they had better hurry," Wingate said tersely.
