"That I know no more than you do."

"C'est un vrai mystère."

"From day to day I live in hope that the real criminal will be discovered and brought to justice; but with each day that passes that hope grows fainter within me."

"I know not what to say.--When I remember the past, and when I look round and think that this is now the home of you and madame"----He spread out his hands with a gesture more expressive than words.

Before more could be said, there came a peculiar knock at the door--three taps in quick succession, followed by a fourth after a longer interval. At the sound, Clara and Miss Primby emerged from the other room.

"That summons is intended for me," said Karovsky quickly as he rose and opened the door.

Then those inside saw that a man, a stranger, was standing on the landing, who seemed to retire further into the shade the moment the light fell on him. He said something rapidly in a low voice to Karovsky, to which the latter replied in the same language. Then the Russian gave a nod as of dismissal, and closing the door, turned and confronted Gerald with a grave face and distended eyes. "That man is one of us," he said. "When I entered the house, I left him on watch outside. He now comes to tell me that a policeman in plain clothes is on guard outside the court, and that another is stationed inside, so that no one can pass in or out without being observed. He also tells me that there are two more constables in uniform patrolling the street close by; and that from what he can gather, they are waiting the arrival of some one, probably a superior officer. Is it possible, Brooke, that you can be the quarry on which they intend presently to swoop?"

"There can be little doubt of it," answered Gerald, who had risen to his feet while Karovsky was speaking. He had turned very pale; but his lips were firm-set, and the expression which shone out of his eyes was something far removed from craven fear.

Clara stood with one hand resting on the table, her frame trembling slightly. Was the blow she had dreaded so long about to fall at last?

Miss Primby sat down with a gasp.
