"Your father," said Mask. "Johnstone!"

The red-bearded clerk entered, and when within, removed a false beard and a wig.

"Father," cried Allen, rising. It was indeed Mr. Hill, pale and trembling.

CHAPTER XVI

[MR. HILL'S STORY]

Allen was so thunderstruck at the sight of his father, who had so unexpectedly appeared, that he could only stand silently staring. Mr. Hill gave a nervous titter, and tried to appear at his ease. But the sight of his pale face and trembling limbs shewed that the man was possessed by terror. Also he locked the door while Allen gaped. It was Mask who spoke first.

"You are surprised to find your father as my clerk," he said smoothly to Allen; "but when he came to me asking to be concealed, I arranged that Johnstone should take a much-needed holiday at the sea-side. I believe he is at Brighton," said Mr. Mask deliberately. "In the meantime, your father, by means of a clever disguise, adopted Johnstone's name, and personality, and looks. In the dim light of the office every one thinks he is Johnstone, and to tell you the truth," said Mr. Mask, smiling, "my clients are so possessed by their own fears, that they take very little notice of my clerk."

Allen scarcely listened to the half of this explanation. "Father," he cried, "whatever is the meaning of all this?"

Hill tittered again, and looked about for a seat as his limbs would hardly support him. As Mr. Mask had one chair, and Allen the other, it looked as though Hill would have to sink on the floor. But Allen pushed forward his own chair and made his father sit down. Then, so white was the man, that he produced his flask, and gave him a nip of brandy. "I never travel without this," said Allen, alluding to the flask. "It comes in handy at times," and he spoke this irrelevantly so as to put Hill at his ease.

The little man, under the grotesque mask of Johnstone, grew braver after the brandy, with Dutch courage. "You did not expect to find me here, Allen?" he said, with his nervous titter.
