The man laughed a low, harsh laugh and turned away.

"I demand to know where my friend is!" I cried, stepping after him across the room, and facing him again.

"My dear Royle," he replied, in that curious, high-pitched voice, yet with a calm, irritating demeanour. "Haven't I already told you I am your friend?"

"It's a lie! You are not Sir Digby!" I cried angrily. "I shall inform the police that I've found you usurping his place and name, and leave them to solve the mystery."

"Act just as you think fit, my dear old fellow," he laughed. "Perhaps the police might discover more than you yourself would care for them to know."

His words caused me to ponder. At what could he be hinting?

He saw my hesitancy, and with a sudden movement placed his face close to me, saying:

"My dear fellow look—look into my countenance, you surely can penetrate my disguise. It cannot be so very perfect, surely."

I looked, but turned from him in disgust.

"No. Stop this infernal fooling!" I cried. "I've never seen you before in my life."
